Hooks that your're hooked on.

[Pagan]

That Offspring song is addicting. I can't get enough of it and now I walk around say "I know you wanna hit that." That little tune drives me crazy. I'm also addicted to this stupid rap song where Nelly asks this dude "What tha Hook gon be?" and then the dude replies "I don't need no hook on this beat"but by saying all that they made a hook?

So what song has a hook that you are hooked to?
