In the previous song, Annie Murphy repeatedly sings “I’m a little bit of [whatever it is]”,
where in this song, Ms Brooks sings "I’m a [whatever it is, though the word “bitch” is often used].
While “I’m a” is a contraction-of-sorts of “I’m a little bit of”, the tautology is sufficient, IMO, to constitute an adequate connection for the purpose of this community.
This song was produced by the same engineer as Holiday in Cambodia, Geza X. He also recorded with Black Flag and Germs. He had a band called Geza X and the Mommymen. Their album is critically underrated.
