One song is currently (as in while I'm typing these first few lines) stuck in my head:
Relapse - Jesse McCartney
Every time I leave, every time I leave
I keep coming back every time I leave!
It's weird cos I'm listening to Twilight Soundtrack and I'm still singing that line of the song.
Oh, I wanna share my favorite Twilight song from Muse. It's called Supermassive Black Hole. It's a catchy song and it's really good.
