Yes, post makes sense. Have experienced, yes. All the time there are songs in my head. Lots of repetition. Can't see how it'd be anything BP related.

I think songs in people's heads are very common. The over and over and over thing might have a whiff of OCD trait about it, but even so, a trait does not a disorder make. And.... still, I don't even think it's that, though that is my personal opinion (I do have OCD). Not being able to make it stop... well..while I can see how that might seem so too... But everyone gets songs stuck in their heads (alas, so often annoying ones, lol!) I wouldn't worry about this (in case you are, not sure).
