I get songs stuck in my head like most other people. I think this is probably normal and nothing to worry about. The ones that worry me are the ones that mean something and just won't go away. Two particular songs were very meaningful to a relationship I was in that just ended, and I frequently get them stuck in my head for what seems like hours. I think this is probably my OCD kicking in. Don't think it is a big enough problem to change meds for, but I should probably talk to my therapist about it.
