This one isn't for the kids - I mean a T-Swift album deep cut vs an Arctic Monkeys b-side which is basically a remake of the 1965 Paramounts cover of Baby I'm Yours by Barbara Lewis?
NICHE! I actually wanted to use the Paramounts version, or the Cass Eliott version but couldn't find a decent version to extract from, and the Cass one has annoying piano in it, so Arctics it is.
But it's a mashup about loving yourself and basically realising it's up to you, kid and only you yourself, baby.
