i don't have a favourite composer per se but there's some series i love the shit out of the soundtracks of... 07th expansion's stuff is always great (except rose gun days we don't talk about rose gun days) and umineko and higanbana have g r e a t music, i love every track.. higurashi too i guess but the original vn's soundtrack for that is sort of limited ahaha

and the best soundtrack from a show not part of a series is definitely shiki.. holy shit, that ost just blew me away, it fits so well with the series but is also really nice to listen to outside of it.. IDEK WHO THE COMPOSER WAS BUT I GUESS THEY'RE MY FAVOURITE NOW i'm still listening to that shit and i think the anime aired in what.. 2010.. i feel old
