Cover art for For Today I Am a Boy lyrics by Antony and the Johnsons

against_me, i'm think it is "a womb within me." i've always heard that as well. it seems like "i know whom within me" isn't enough syllables to match the song. and plus, it doesn't even make a whole lot of sense. "a womb" fits a lot better.
