I dig Nirvana, they get a bad rap from a lot of my friends though.
And FD you definitely need to listen to a whole lot of Frank Zappa if you're not familiar. He was a musical genius, all his music is brilliant and almost all his lyrics are hilarious. That song, Muffin Man, Bobby Brown, and Don't Eat That Yellow Snow (full) are good starting points, they're what got me into him.
