There are so many good soundtracks. My top three favorites would be. Thats quite an exclusive list since I have seen dozens of movies and around a hundred series. Netflix for the win.

1. Gantz
2. Please Teacher
3. Naruto

Hmm, yeah. I kinda like the Standalone Complex 1st gig soundtrack, 2nd not so much. Other than that, I think the music in almost all of Miyazaki's work is excellent. :)
Oh and Cowboy Bebop, man i like that music. :)

haruka kanata, kanashime wo yasashisa nii, and GO! in naruto all good

Every Gundam Series as they use real artists.
