A MusicBrainz release represents the unique release (i.e. issuing) of a product on a specific date with specific release information such as the country, label, barcode, packaging, etc. If you walk into a store and purchase an album or single, they're each represented in MusicBrainz as one release.
Each release belongs to a release group and contains at least one medium (commonly referred to as a disc when talking about a CD release). Each medium has a tracklist.
A medium is the actual physical medium the audio content is stored upon. This means that each CD in a multi-disc release will be entered as separate mediums within the release, and that both sides of a vinyl record or cassette will exist on one medium. Mediums have a format (e.g. CD, DVD, vinyl, cassette) and can optionally also have a title.
Tracklists represent the set and ordering of tracks as listed on a liner, and the same tracklist can appear on more than one release. For example, a boxset compilation that contains previously released CDs would share the same tracklists as the separate releases.
- CD single: Creep
- 2xCD album: The Fragile
- Vinyl single: Feel the Music
- 2xVinyl album: Blonde on Blonde

This is a number assigned to the release by the label which can often be found on the spine or near the barcode. There may be more than one, especially when multiple labels are involved. This is not the ASIN — there is a relationship for that — nor the label code.
