I've always considered myself skilled at not getting songs stuck in my head. An important skill, considering the songs most likely to get stuck in one's head are often annoyingly bad songs.
Somehow a few songs have penetrated my defenses. For over a month now I've had a handful of songs stuck in my head that, no matter what I do, I can't get rid of. Literally every night when I go to sleep, I've got one of these ringing through my head, and I'm doomed.
Oh well. At least I'm finally past "Still Alive".
