^^I don't know. I think I've heard her explicitly state that her idea of music is physical rather than cerebral. She said something to the effect that she doesn't think music is about picking out meanings behind word usage, but rather that it's about the physical sensation that it gives you at the moment. Like, does it make you sick? Does it make you feel like dancing? Does it make you want to hit somebody?
Plus, she has this kind of blazing fearlessness about her. Not that INFPs couldn't have that, but it's not the usual "vibe" I get from them.
I think PJ has the same type as a doc who checked my nuts for lumps the other day: so/sp e54 istp. Receptionist was a prickly little sp/so e89, the nurse an so/sp e98, both also istps. Her ties, and inevitable difficulties, with sx/sp e54 infp Nick Cave come to mind.
Prod me for specifics if you're on the certain side of the fence.
