A single recording can be connected to several dates, and those dates do not describe the same event.
A song may be written in one year, recorded in another, registered with a rights organisation later, mentioned publicly after that and leaked long before it receives an official release. In some cases, only one of those dates is known. In others, several can be documented.
Problems begin when one date is used as a substitute for another. A file that circulated in 2024 was not necessarily recorded in 2024. A publishing registration does not prove that vocals had already been recorded. An official release date does not tell us when an earlier demo was made.
EverySongBy keeps these events separate. Where reliable information exists, catalogue entries can show a recording date or period, a first public appearance, a reported circulation or leak date and a later official release date. When a date cannot be supported, the catalogue says so rather than guessing.
Why date labels matter
Dates shape the history attached to a recording. They can connect a song to an album era, a writing session, a collaborator, an abandoned project or a later revival.
An incorrect date can create a false story. It may suggest that:
- A song was intended for an album that did not yet exist
- An artist recorded a response to an event that happened later
- A collaboration took place during the wrong period
- A leaked file was newly recorded when it was actually several years old
- A demo followed a commercial release when it really came first
- Two versions belong to the same session when they do not
Clear date labels make the catalogue more useful without pretending that every session can be reconstructed precisely.
The main dates used in a recording history
Several dates may be relevant to one song. Each answers a different question.
Writing date
The writing date describes when the composition was created or developed.
This may be supported by:
- A songwriter or producer interview
- A dated session document
- A studio diary or photograph
- A collaborator’s account
- A documentary or behind-the-scenes recording
- A reliable account of an album-writing period
A writing date does not prove that a finished recording was made on the same day. A song can be written before vocals are recorded, rewritten across several sessions or registered before a final performance exists.
When only the writing period is known, the catalogue should describe it as writing or session context rather than presenting it as an exact recording date.
Recording date
The recording date describes when the relevant vocal or instrumental performance was captured.
This is often the most useful date for distinguishing demos, rerecordings and alternate versions. It can show whether two recordings came from the same session or whether an artist returned to the song years later.
Reliable evidence may include:
- Session logs
- Studio records
- Original multitrack or master documentation
- Liner notes
- Producer, engineer or artist statements
- Legal or label documents
- Official archival releases
Exact recording dates are uncommon for many unreleased songs. A supported year, period or project era is often more honest than a precise day copied from an uncertain source.
Registration date
A registration date is the date a composition or recording was entered into a publishing, copyright or rights-management database.
Registrations can help establish that a title existed by a certain point. They may also identify writers, publishers, alternate titles or work numbers.
However, a registration date is not automatically:
- The writing date
- The recording date
- The date vocals were completed
- The date a song was pitched
- The date a file leaked
- The date the public first heard it
Some works are registered long after they were written. Others are registered before recording begins. A composition can also be registered without the named artist ever recording it.
First public mention
The first public mention is the earliest supported occasion on which a title or recording was discussed openly.
This may come from:
- An interview
- A track list
- A producer or collaborator post
- An auction or sale listing
- A publishing entry that became publicly searchable
- A documentary or studio clip
- An announcement for a project that was later cancelled
A public mention can confirm that a title was known, but it may not confirm that a complete recording existed. The wording should reflect whether the source refers to a song, a session, a planned track or finished audio.
Snippet or preview date
A snippet date records when a short piece of audio became publicly available or was heard in a documented setting.
The source might be:
- An official social-media preview
- A livestream
- A documentary
- A studio video
- A commercial or trailer
- An auction preview
- An unauthorised excerpt
A snippet establishes that some audio was present at that time. It does not necessarily prove that a complete recording existed, and it should not be described as a full leak unless the complete track was also known to circulate.
Circulation or leak date
A circulation or leak date describes when unauthorised audio was first reported as moving beyond its private or intended audience.
The term leak date can sound more precise than the evidence allows. In practice, researchers may only know:
- When a snippet first appeared
- When a file was first discussed publicly
- When a complete recording was first reported in circulation
- When it reached a larger fan community
- When a file was reposted or rediscovered
The earliest widely noticed date may not be the true first leak. Files can circulate privately for months or years before they become publicly documented.
For that reason, EverySongBy uses wording such as Reported leak, Reported in circulation or First publicly documented circulation when the exact origin cannot be proved.
Official release date
The official release date is when the recording received an authorised public release from the artist, label or rights holder.
This may be:
- A digital single date
- An album-release date
- A physical single date
- A soundtrack release
- An authorised archival or deluxe-edition release
- A posthumous release
An official release can happen years after the recording was made or after unauthorised copies circulated. The earlier demo or leaked version may still deserve a separate entry when it contains a different performance, title, arrangement, lyric or vocal.
One recording can need several dates
A single catalogue entry may legitimately show more than one date.
For example:
- Recorded: 2013
- Snippet appeared: 2019
- Reported leak: 2024
- Officially released: 2026
Those dates describe four different stages in the recording’s history. Reducing the entry to 2024 would make the song look newly recorded at the time of the leak. Reducing it to 2026 would erase the earlier circulation history.
The About this recording text can explain how the dates relate to one another and whether the officially released version is the same master or a later version.
Why a leak date is not a recording date
This is one of the most common mistakes in unreleased-song lists.
A file appearing online tells us when that file became publicly known, not when the performance was recorded. The audio may come from:
- A recent session
- An album project from several years earlier
- An old songwriter demo
- An abandoned soundtrack
- An archival recording
- A compilation of stems from different periods
Unless the session date is independently supported, the catalogue should not copy the leak year into the recording-year field.
Where no recording date is known, the entry can show the reported circulation date while stating that the recording period remains unconfirmed.
Why a release date is not a recording date
Official releases are frequently recorded well before the public receives them.
Delays may result from:
- Album scheduling
- Soundtrack production
- Clearance or licensing
- Changes in label strategy
- A postponed collaboration
- An archival project
- A later decision to release an old demo
The release year is still important, but it should not be used to place the recording inside an artist’s creative timeline when stronger session information shows that it belongs to an earlier period.
Exact dates, years and recording periods
Dates should be displayed at the level of precision supported by the evidence.
Exact date
Use an exact day only when a reliable source supports it. This is most common for official releases and sometimes possible for documented sessions, broadcasts or public previews.
Year only
Use a year when the recording can be placed reliably within that calendar year but the exact day or month is not known.
Recording period
Use a period such as 2011–2012, during the album sessions or early 2010s when the evidence supports a range rather than one precise year.
Approximate date
Use wording such as circa 2013 only when there is a reasonable basis for the estimate. Approximate language should not be added merely because a nearby project seems plausible.
Unknown date
Use Unknown date or Recording date not confirmed when no supported chronology is available.
An unknown date is more accurate than a guessed one.
How year ranges should be interpreted
A range does not mean the song was continuously recorded across every year shown. It means the available evidence places the session somewhere within that period.
Ranges can be useful when:
- An album was developed across two calendar years
- A collaborator remembers the era but not the exact session
- Different sources give nearby years
- A song changed across several sessions
- The first known version and later revision were recorded separately
The accompanying background should explain what the range refers to whenever possible.
File dates are weak evidence
A date embedded in a circulating filename or file properties can be useful, but it is rarely conclusive.
File metadata can change when audio is:
- Exported again
- Transferred between devices
- Uploaded to a new service
- Edited or converted
- Renamed by another person
- Restored from an archive
- Packaged inside a later collection
A filename such as Song Title 2017 Final may reflect a genuine session label, a later guess or somebody’s attempt to organise files.
EverySongBy does not treat filenames or file timestamps as definitive without supporting context.
Community documentation and first-known dates
Fan-maintained databases and community archives can be valuable for identifying when a title, snippet or file first became widely discussed.
They are particularly useful for:
- Locating an older post or archived discussion
- Distinguishing a snippet from a later complete leak
- Tracing alternate filenames
- Finding leads for interviews or registrations
- Recognising when a supposedly new leak had circulated before
However, community dates should be labelled as community documentation and checked against earlier evidence where possible. A database’s added date may describe when its own page was created, not when the recording first circulated.
Regional release dates
A song can have more than one authorised release date.
For example, it may be:
- Released digitally in one country before another
- Issued as an album track before becoming a single
- Available on a soundtrack before a later artist release
- Sent to radio before receiving a commercial single release
- Released physically after becoming available for streaming
The catalogue should use the earliest relevant authorised public release for the recording, while the background can mention important regional or format differences.
Popularity information should also specify the market being discussed. A UK chart date, a US chart entry and a worldwide streaming revival are different forms of context.
First release versus later rerelease
A rerelease does not reset the recording’s original release date.
The same master may later appear on:
- A deluxe edition
- A greatest-hits collection
- A remastered album
- A soundtrack
- A viral or anniversary campaign
- A new physical format
These later appearances can be historically important, but they do not make the underlying recording new.
A newly performed rerecording, however, receives its own recording date and release history.
When an unreleased song becomes official
An unreleased recording may later receive an authorised release.
When that happens, the catalogue should determine whether the official release is:
- The same master that circulated earlier
- A remastered version of the earlier recording
- A newly mixed version using the same vocals
- A partial reconstruction
- A rerecording
- A different version with revised lyrics or production
The entry can move into the official section when appropriate, but its earlier history should not disappear.
A separate demo or circulating version can remain in the catalogue when it contains a meaningfully different performance.
Demos intended for other artists
Songwriter demos often involve several dates that are easy to confuse.
A demo can have:
- A writing or recording date
- A date when it was pitched to an intended performer
- A date when the final performer recorded a new version
- A circulation or leak date for the songwriter’s demo
- An official release date for the final commercial recording
The final performer’s release date does not date the songwriter’s demo. The two recordings should retain their own chronologies.
Where supported, the demo entry can show the intended performer and name the later released version inside About this recording.
Posthumous and archival releases
Posthumous releases may combine material from several periods.
A final release can include:
- Vocals recorded during the artist’s lifetime
- New production completed later
- Guest vocals added after the original session
- Fragments taken from another recording
- An archival demo edited into a finished song
The release date describes when the finished product became public. It does not replace the date or period of the artist’s original vocal.
The catalogue should explain both stages when the information is available.
Manipulated and artificially generated audio
A claimed leak date means little if the recording itself is not authentic.
Audio can be:
- Generated with a cloned voice
- Created from isolated stems
- Edited from several unrelated recordings
- Pitched or processed to resemble another artist
- Placed over a new instrumental
- Presented with a fabricated session date
A recent upload of manipulated audio should not become a new catalogue entry simply because it has a clear online date.
Authenticity must be considered before chronology.
How dates are shown in the catalogue
The date area is designed to show what each date represents rather than presenting one unexplained year.
Depending on the evidence, an entry may display:
- Recorded
- Recording period
- First public mention
- Snippet appeared
- Reported leak
- Reported in circulation
- Officially released
- Unknown date
Not every entry needs every field. The catalogue shows only the dates that add useful, supportable context.
How chronological sorting works
The catalogue opens with the newest known dates first so recent releases and newly documented material are easier to find.
Chronological sorting uses supported dates rather than alphabetical order or the date a page was edited. Exact dates, year-only dates and recording periods are handled consistently, while entries without a usable date appear after dated records.
Sorting does not change what a date means. A reported leak year remains a circulation date, not a recording year.
Sources used to establish dates
Useful date evidence may come from:
- Official releases and liner notes
- Label and artist announcements
- Producer, songwriter and engineer interviews
- Session logs and studio documentation
- Publishing and copyright records
- Archived websites and social posts
- Documentaries and broadcast records
- Reputable music journalism
- Legal, auction or archival documents
- Community documentation used as a clearly labelled lead
The strongest chronology usually comes from several sources that describe different stages of the song’s history.
What to do when sources disagree
Two sources may give different years because they are describing different events.
One may identify the writing session, another the vocal recording and another the first public appearance. Before treating them as contradictory, the catalogue should ask what each date actually refers to.
When sources genuinely conflict, the entry can use:
- A supported range
- An approximate period
- The better-documented date with a note about the disagreement
- Unknown date when neither claim is reliable enough
Uncertainty should remain visible rather than being silently converted into an exact year.
A practical date checklist
When assigning dates to a recording, ask:
- Does this date describe writing, recording, registration, circulation or release?
- Is the exact day supported, or only the year?
- Could the date come from a later file export or repost?
- Is a snippet being confused with a complete leak?
- Was the file already circulating privately before the reported date?
- Does the release date belong to this recording or a later version?
- Is the song tied to a confirmed project or merely a similar era?
- Do regional release dates differ?
- Is the recording authentic?
- Would a range or unknown date be more accurate?
- Does the background explain how the dates relate?
Corrections and changing evidence
Recording histories can become clearer years later. An anniversary release may publish a session date, a producer may identify when a demo was made, or an official release may confirm that a circulating file came from an earlier project.
EverySongBy reviews dates when stronger evidence appears.
Corrections are most useful when they include an original credit, interview, archived page, registration record, catalogue number, scan, timestamp or enough context to distinguish the date being proposed.
The aim is an honest timeline
A useful catalogue does not force every recording into one unexplained year.
It distinguishes when a song was written, when a performance was recorded, when a title became public, when audio circulated and when an authorised release finally appeared.
Those events can be separated by months, years or even decades.
The goal is not to create false precision. It is to give each recording the clearest supported timeline available and to leave dates unknown when the evidence does not justify a stronger claim.
