So I was driving today and "Rebel Rebel" came on the radio. I'm not a David Bowie fan by any stretch of the imagination, but I always find myself turning this song way, way up. The guitar riff in it is just so catchy and really grabs you. In the spirit of my realization today, I thought I'd make a discussion thread.
In your opinions, what is/are are the catchiest riffs out there?
