Absolute Anime

Hi, I added some Anime songs to my iPod and would like to know the names of the artist/bands that did them. I'll list them off

Kare Kano - Yume no Naka e

Neon Genesis Evangelion - Cruel Angel's thesis
NGE - Cruel Angel's thesis (Ayanami Remix)
NGE - Cruel Angel's thesis (piano version)

Slayers - Get along

Super GALS - Aitsu

Thats all for now, i may have more

the slayers song, get along, is by Megumi Hayashibara & Okui Masami. I think
and super GALS - aitsu is by Kotobuki Ran. Please let me know if I got anything wrong
