My favourite cartoon music is from Peanuts, the Raccoons, Ren and Stimpy, Rock and Rule, Urusei Yatsura, Lupin the Third and the Dirty Pair. It's a pretty mismatched list, but I have fairly wide-ranging tastes, I guess. I can't stand most of the cartoon music these days though, specifically the generic techno/fast hip-hop stuff they use in virtually EVERY modern action-cartoon.
I don't think the phrase "et al" applies, unless the things you're listing are similar, and people can guess what the rest of the sentence will be, like this: "I like Tiny Toons, Taz-Mania, Hysteria, et al". One would assume you also mean Pinky and the Brain or Animaniacs, or whatever. You can't just say something like "Peanuts, Akira, Heroes et al," which is basically what you did. Out of curiosity, what else were you referring to in the "et al" part?
