In high school, a teacher of mine gave the class a side assignment during a poetry unit to bring in a song that we thought qualified as poetry. I struggled to find one since I loved music so much. But, in the days of no internet and limited resources at home, I never did find anything to bring. Man, I wish I'd known this song then. I would have knocked the class's collective socks clean off.
Also, "We're just a habit, like saccharine." is probably the best line in any song ever. EVER.
