3. Prince - Super Bowl XLI (2007)
No one is cooler than Prince. It's a scientific fact. Exhibit A: in 2007, fighting off the Miami rain, he ripped through gnarly renditions of the Purple Rain classics "Let's Go Crazy," "Baby, I'm a Star," and, naturally, a mammoth "Purple Rain." But it was his funked-up cover of Foo Fighters' "Best of You" – totally random, yet completely awesome – that still had people buzzing weeks after this gig.
