hahaha well to each his own i suppose, though i must say that the type of music doesn't really speak to me much either, but the satire of it all, that's what makes it funny to me.
i do like the song you posted though, the old metallica rocks, their last cd is pretty good too.
mostly into rock and metal myself but i enjoy the more comedic bands like weird al yankovic and stuff like the lonely island, though that's probably because i focus on the lyrics more than the music.
