The folks over at Current TV counted down the top five best-selling songs of the past decade, according to Billboard. The list offers one unavoidable truth: We, collectively as Americans, have awful taste. Four of these five songs are objectively not good. (Let's call them the "aught-nots.") The last one -- Usher's "Yeah!" -- just reminds us how much we miss Lil Jon. (What? Yeah!)

Take a look and remember the songs you're now ashamed you ever sang in the shower. Oh, and marvel at the awesome belt buckle that host Sergio Cilli sports.
