Style / Release Group

Status: This is an official style guideline.


See the guidelines for recording and release group titles for how to enter the release group's title.


The artist should usually be the same as the first release.

Secondary types

Any secondary types should apply to most of the tracks on the releases within the release group. It's OK if some of the tracks do not fit the type (for example, if a live album has some bonus studio tracks), as long as the type applies to the releases overall.

The following are not generally considered compilations and shouldn't be marked with the Compilation secondary type:

There is a certain amount of crossover within the definition of compilation and the other types of release. Compilation should be used in addition to, not instead of, other types: for example, a various artists soundtrack using pre-released music should be marked as both a soundtrack and a compilation. As a general rule, always select every secondary type that applies.

A computer game CD with audio tracks should be classified as a soundtrack.

What should be grouped together?

Release groups should be used to group variations of the same release. The following are examples of things which should normally be grouped together in the same release group:

This includes those where the tracklist isn't identical, such as releases which have bonus tracks or even bonus discs.


What should not be grouped together?

There are a number of situations where it is not appropriate for releases to be part of the same release group:


Other situations

There are a number of situations where there is currently no consensus about whether releases should be grouped together or not. This includes the same album sung in different languages, re-recorded albums and remixed albums. Be aware that attempting to group these releases can be quite controversial. If in doubt, these releases should probably be in separate release groups.
