At their lowest level, albums and tracks are identified by UPC/ISRC. Each UPC/ISRC can only be associated with one project – we cannot show the same UPC/ISRC in multiple projects.
The Maroon 5 track ‘Moves Like Jagger’ is linked to the ‘Hands All Over’ project, released in 2011.
In 2015, Maroon 5 released a greatest hits compilation, ‘Singles’, which includes the track ‘Moves Like Jagger’. However, as the track was already linked to the ‘Hands All Over’ project, it is not associated with the ‘Singles’ project. The same is true of the rest of the tracks from the ‘Singles’ compilation, therefore no tracks are associated with this album:
As such no track consumption will be attributed to the ‘Singles’ project, consumption of the tracks on this compilation will be attributed to the projects that those tracks are linked to (including ‘Hands All Over’):
This is also why tracks are not usually included in projects for live albums. The exception is if a new track appears first on a live album, in which case MDM will create a new artist/title grouping for that track and associate it with the live album.
