Stuck in my head

The things that are always stuck in my head are usually important at least lately. Such as school I keep thinking about all my home work I have to make up since i was gone for a week and I also have my SATs on the same day as Prom. Its really not exciting making up all that work and studding for SATs. lol I think about work and how much money I need to pay my bills every month. I do as everyone else typically get songs stuck in my head. which ones kind of depend on my mood i suppose.
