The ReleaseDate is the date in which a release was made available through some sort of distribution mechanism. For example, this may be via a retail store, being published as a free download on a website or distributed to industry insiders (in the case of promotional releases) amongst other mechanisms.
What a Release Date is not
- A copyright date: A release date is NOT the same as a copyright date off a disc liner or vinyl cover. It can be a useful indication for releases from obscure sources; however in the general case it is not correct. Often a copyright date can precede the year of release, if the actual release was in January. Often re-releases/re-issues will carry the copyright date of the original release rather than the year they were re-issued.
- A performance date: In the case of live performance bootlegs, the ReleaseDate is a different concept to the performance date. The concert may have occurred on 2007-08-03, but it may have taken some time for the bootleg to be produced, tracks split and packaged for CD (or other ReleaseFormat) release. See LiveBootlegStyle for an attempt to structure the capture of this information with the current MusicBrainz database structure.
- An import date: Amazon (and other retailers) often have listings for releases marked as "IMPORT". Dates for these releases should never be used as release dates; they most often represent when the retailer imported the release from its original release country and added to their database for sale. This is an incorrect release date to use; instead the release date for the home country of release should be sought, either from a different Amazon domain, or a different (local) retailer site.
Differences between countries
The ReleaseDate of the same release in different countries may differ by several days or several weeks. For example, typically CD releases from mainstream distributors and released on different days of the week in different countries, e.g. (non-exhaustive, and not a general rule)
|UK/Ireland Downloads (some labels)||Sunday|
|most European countries, Australia & New Zealand||Monday|
|Germany||Friday (was Monday before summer 2005)|
Sources for release dates
Since a copyright date is not a reliable source (only an indicative source), the release date will usually need to be sourced online. Possible sources include
- online retail stores
- label sites
- official artist discographies
- other online music databases (Discogs, Wikipedia etc)
All sources have varying degrees of reliability, differing by type of music, format of release and age of release. To be sure you may often need to cross-reference between several stores or sources. Note that many sources will not distinguish between countries reliably so one should be careful that the ReleaseDate one chooses matches the ReleaseCountry set.
- Amazon.com has many ASINs with 1990-10-25 as the release date. This is a bogus date representing when Amazon first went into operation, so if present don't enter it in MusicBrainz (the system will warn you).
- Amazon usually has two dates on its releases, the Original Release Date and another Audio CD or LP date on the line above. Almost always, the top date is more likely to be correct. The bottom date usually represents the original release, which may be on a different media, have different numbers of tracks, be non-remastered etc. It can also sometimes mean the originally announced release date; so if the actual release gets delayed by several weeks these dates may be several weeks apart. In both cases, the top date should almost always be used; subject to a general judgement on the reliability of the Amazon information (and confirmation with another source if possible).
- Discogs has extremely varied reliability of its release dates; especially where it notes down to a specific day of the month. Sometimes release countries are wrong. Please try and be especially careful to cross-check a day-specific date that is sourced from Discogs.
- Wikipedia often does not say which country a release date is for; often only the home country of release. Please ensure that the date applies to the country your release is from using a second source.
- iTunes often displays a release date from when the first version of an album/single was first made available to the iTunes Store as a whole, often not the same date as when other versions were released to a specific territory. Do not rely on the date shown and check other download stores from your country to verify the correct digital release date.
