Here's the thing with me and musicians. Most of my favourite musicians are either broken up bands, dead people, in really obscure/experimental genres, または groups that I like quite a bit but wouldn't call "favourites". I get much もっと見る excited about individual songs than I do bands. I see bands/groups/singers もっと見る of like... collections of songs rather than producers of them? If that makes sense. I care about the individual songs もっと見る and less about the band/group/singer itself. If that makes sense?
ANYWAY, TL;DR explanation aside. One of the few recognisable, not dead bands/groups that I do consider a favourite is 天使 and Airwaves.
