Release types for TrackReleases
In the ReleaseList
of ERN-3, it is in many* cases not only correct but mandatory to include
multiple Releases:
One to represent the main release and
One for each track on the release (the so-called "Track Releases").
The Main Release is identified by the ReleaseType
value of, for instance, "Album
" (for traditional albums) or "Single
" (typically used for Releases with one track released in a distinct package from an album, or occasionally a few tracks).
It is, however, incorrect to use the value "Single
" for the track-level Releases. These must instead be identified by the ReleaseType
of "TrackRelease
" or "VideoTrackRelease
".
ERN-4 does not support different types for Track Releases.
*) There are a number of profiles that do not allow any Track Releases (Ringtones, MidiRingtones, Long-form Music Videos, TV Series Releases, Film Bundle Releases, Wall Paper Releases, Simple Video Single and Single Resource Release). In those cases, an ERN message would typically only contain one Release.
