Those are all good...
Metalocolypse! Dethklock RULES!
I like that one song from Family Guy where Peter sings about the house the Griffins get from Lois's Aunt:
"My God this House is Freakin' Sweet."
I also like the song from Slackers when the three guys are doing that whole best friends montage (including a StarWars-ish, armor and shooting blasters clip) I think its called, "3 is The Magic Number." Also most of the songs written by Jason Shwartzman in the movie.
The Boondocks theme song.
Cowboy Beebop soundtrack, including the episode "Mushroom Hunting."
The Venture Bros.
Rock, punk, Emo, Metal...lately Ive been listening to a lot of Tool.
"Kom'rk tsad droten troch nyn ures adenn, Dha Werda Verda a'den tratu."
