What's the Song of Summer 2008?

You know, I'm not gonna lie: kind of a tame summer for music, don't you think? Not to say that there weren't solid releases from big names, but it's that time of year when everyone seems to be singing the same song ("Umbrella-ella-ella-ella!") and yet I can't seem to find a consensus of what songs are perpetually on the radio, in our heads, or on the dance floor.

But here are the songs that, as far as I can tell, are on heavy rotation right now. You know, the songs that will remind us in the future of that one summer when every superhero movie ever came out, Mariah Carey got married, and neither Obama nor McCain was president yet.
