"The kiosk in my temporal lobe is shaped like Rosalynn Carter."
TMV's lyrics used to bother me a lot more. But then I imagined if I could insert coherent lyrics against the frenzy of music. I don't think there's any better lyrical style to fit their music. It's chaotic and ultimately strange, and needs suitable lyrics. If Bob Dylan wrote lyrics to TMV, they would be really out of place.
Hell, I have no clue what he's saying in Spanish, and it's probably just as incoherent as English. Sometimes I don't notice when he changes languages. That shows you how closely I pay attention to the actual ideas behind the words.
