I found the bug with track 9 of the Final Fantasy XII soundtrack, disc 1. The track is titled "The Royal City of Rabanastre / Town Ward Upper Stratum".
It looks to me like there's some old code for parsing CDDB data still sticking around. libjuicer/sj-metadata-musicbrainz.c, artist_and_title_from_title() complete with comment: /* Data imported from FreeDB is horrendeous for compilations, * Try to split the 'Various' artist */ -- bad parsing of musicbrainz data https://launchpad.net/bugs/72799 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
