How to Kill an Earworm

Anyone have any good advice on how to get earworms out of your head? I have had Cat Stevens' Peace Train stuck in my head for like a week now and it's about to drive me insane!!!:banghead: I have tried listening to Peace Train several times, it's still stuck their. I have tried listening to Led Zeppelin, Korn, Pink Floyd, Godsmack, The Beatles, Chingy, AC/DC, Stone Temple Pilots and when I finish listening to music I still go back to freakin Cat Steven's lol!

I've even tried listening to some of my favorite songs from my bandgeek days and I'm about ready to find a Peace Train to run my head over so I don't have to listen to it anymore lol!:D:violent1:

So what do you guys and gals do when you get an earworm?
