However and also, the grammatical inaccuracy in the song -- "you and me could write a bad romance" -- while utterly overlookable in the song's general fabulosity, brings up a to-me interesting point, which is that the correct phrasing -- "you and I could write a bad romance" -- would actually sound BETTER, in my humble opinion, because of the repeated "I" sound.
And there you have it. Go about your business.
