I've spent this evening working through the first three Goldfrapp albums because I never paid much attention to them before, apart from a couple of songs.
I really like it! Alison Goldfrapp's voice is wonderful, and the songs themselves are varied too.
I do love TAMUSIC as well, I have numerous albums of theirs. The three Madoka arrange albums especially are fantastic works.
I really wish that such doujin albums were easily available to buy though. I only have a couple of Alstroemeria Records CDs that I managed to luck upon at Japan Expo and bought instantly.
Yup, three that I have at least. Might've been more since, but I usually keep track of these things and I haven't seen anything. Puella Musica, Madoka☆Magica Classic and Mado☆Magi Finale.
