Teeth The Size of Piano Keys is mostly quotes from the poem I'm In Love. Bone Palace Ballet is named after a book of poetry and I believe a few other songs have quotes as well.
I think Craig's old lyrics were a lot better too, but DRUGS lyrics are not as bad as people make them seem. And they certainly are not the worst around.
Yeah, I just compared I'm In Love to Teeth a few minutes ago, and it's crazy all the references.
I find DRUGS lyrics lame, especially "Sex Life", because if there's one thing I hate, it's people who have to call out "haters". Sounds so juvenile.
