Looks like I might be bringing up old threads. They're new to me though, so here it goes!
I can't place them in a certain order since I like them for different reasons. Same deal when it comes to anime.
After Dark - Asian Kung-fu Generation; Bleach OP 7 (I also liked a few more from this anime)
* Super Shooter - RIP Slyme; Gantz OP
* Akaneiro Ga Moeru Toki (When the Sunset turns Red) - Scoobie Doo; Gungrave ending
Forever We Can Make it - Thyme; I can't remember which anime it was from. I just know I only liked the song. OP
Crawl - Veltpunch; Nabari No Ou OP
Sakura Kiss - Chieco Kawabe; Ouran High School Host Club OP
Pretty much the entire sound track from FLCL. I believe all of it was done by The Pillows.
* Songs I like more than others.
*giggles* Subscript.
