Talk:UK Compilation Chart

Criteria for soundtracks
It's not clear which movie soundtracks, specifically musicals, are eligible for UK Albums Chart and which are relegated to UK Compilation Chart.
 * Frozen (soundtrack) was on Compilation in 2014 ref1
 * Moana (soundtrack) was on Albums in 2016 ref2
 * Mamma Mia! The Movie Soundtrack according to the wikipedia article was on Compilation in 2008 but Albums in 2018 (supported by ref3 "The original Mamma Mia movie's accompanying album - now eligible for the Official Albums Chart")
 * All three are on "Official Soundtrack Albums Chart"

ref2 gives some background on the rules:
 * The rules regarding chart eligibility for soundtracks have evolved over the course of the Official Albums Chart’s 60-year history. While the chart used to include albums by ‘Various Artists’ - encompassing soundtracks and compilations, since 1989 a soundtrack is eligible if it’s listed with a single artist credit (for example, ‘Original Cast Recording’), or if there’s a common thread between the songs pulled together for one ‘project’ and usually performed by members of the cast.
 * Albums which feature a collection of previously available songs licensed in to soundtrack and film and with no common artistic link, for example the Fifty Shades soundtracks, qualify for the Official Soundtrack Albums Chart.

The OCC's Rules for Chart Eligibility: Albums: July 2018 page 3 footnote 3 says:
 * Compilation Album Chart Includes
 * original soundtracks unless all tracks feature the same artist or cast,
 * multi orchestral recordings,
 * and “1 artist per side” albums (if not new)

I speculate that
 * what pushes Frozen into the "Compilation" pigeonhole is the inclusion of Demi Lovato's non-soundtrack version of "Let it Go".
 * what changed for Mamma Mia between 2008 and 2018 is that jukebox musicals and or film adaptations of stage musicals count as Album rather than Compilation, whereas previously only original songs would qualify.

It would be nice to confirm or replace these speculations. jnestorius(talk) 23:41, 18 August 2018 (UTC)
