"Hey Ya" or whatever it's called... Everyone told me it was the catchiest song they'd ever heard and that it woul be stuck in my head for days. Now, I don't have anything against rap or hip hop or any of that, but I don't hear the catchiness. I didn't even feel the slightest urge to tap my foot or anything, and five seconds after it ended, I couldn't tell you a single lyrics, phrase or anything from it. I don't get why it's so popular...???
