About anime soundtracks, I’m in doubt because the anime albums will be covered in the database. I think these albums can still be interesting for who wants to see in regular discography, especially the anime soundtracks with tracks originally composed for games, like
Blue Dragon the Animation (Nobuo Uematsu) and
Arc The Lad TV Animation (Masahiro Andoh).
If we use featured option when the music is from a different franchise, I think it may cause some inconsistencies. For example, in Super Mario RPG, Nobuo Uematsu should be assigned as featured, but not Koji Kondo, since the game is part of Super Mario franchise. And both appears in game credits.
