Some that I've been looking for are:

Teen Titans
I especially like a certain song that they played in the very first episode, sometime after they got whipped by the bad guys and again when they ended up on the beach.

Class of 3000
I heard this a few days ago. They were suiting up to battle some aliens...save their friend or something. The music playing was some sort of psychedelic Asian mix kind of song. I liked it.

There are a lot more but at the moment I cant think of them. Feel free to add any music you can think of that's from a cartoon.

i woild like to second the request
