Oh, boy, is it hard to actually rank faves! XD But I'll take a stab at top 10 favorite composers/artists!

3. Yoko Kanno
4. Ryan Farish
5. Kisnou
6. Digitonal
7. Aether
8. DJ Okawari
9. Bonobo

P.S. This list is by no means trying to rank the talent of all these amazing artists. My criteria for ranking was a mix of how many songs I like by these artists and how much I like those songs. (For instance, the songs I like by Yoko Kanno, I like a lot; but I don't own as much of her music as I own of Yuki Kajiura or Sleepy Fish.) The top choices are artists that I like the majority of their work.
