@whatkind: those artists are credited for songs that aren't included on the album so they shouldn't be included in the performer field.

I might have removed some that shouldn't by reverting the edit and relinking everything but keep that in mind.

EDIT: also we generally put the main composer at the beginning of the Performer field, so it's fine to leave Hamaguchi there. Not really a guideline or anything, we just do it sometimes.
