I forgot about this post, but a recent edit made me read the whole subject again.
I never was agree to use classifications for a single track.
Especially for this kind of album (which will make my example too):
TENCHU 3 ORIGINAL SOUND TRACK
There's a single remixed track at the bottom of disc 2, that's 1 track on 62.
Like i said 3 years ago, i think the album should reflete the nature of the content. To me, this album is not a "remix" album. It's classified as an OST.
Since we do not have track by track informations and search, we can only search by "global" classification of an album, so i think global information should be... "global".
