I say lyrics. A song can have a catchy beat, but it gets annoying if the lyrics suck and it gets stuck in your head. For example, I hate the Gorillaz' lyrics, but their beats are pretty good. I say this because I have 'Feel Good Inc.' stuck in my head and I want it to GO AWAY!!! But anyway, hey Tifa's Real Lover(really, did you make this thread because of the FOB/P!atD conflict? xDDD
