I bought a CD today be Yoko Ishida, and it's got some cool music. The last ending theme of Texhonolyze, the opening theme of Ah! My Goddess, some music from Red Ninja: End of Honor, and stuff. Pretty good.
Also, what are some good anime soundtracks to buy? I liked the music in the Mohoromatic one, but if I hear the music from an Anime, I usually want to buy it. And after reading the manga of Mahoromatic, I don't think I want the anime. I looked through the first few pages, and all I saw was intense fanservice. I also saw the Haibane Renmei soundtrack, the Stelvia soundtrack, the Hand Maid May sountrack, and some others.
