There are a few of them. I'll be real...some of the songs that get stuck in my head, man, I have no idea where they come from. For example, I don't listen to "Party in the USA" by Miley Cyrus pretty much ever, and never voluntarily. I haven't heard it recently. But for whatever godforsaken reason, that song popped in my head earlier today. It's probably going to come back now that I'm talking about it.
