26. Wiz Khalifa "Black & Yellow" (2010)
Album: Rolling Papers
With a couple years' hindsight, "Black and Yellow" certainly seems like the starting point of the new Wiz, the pop star who left many of his mixtape fans with mixed feelings. But when the song first dropped, all that mattered was that he did a song with Norwegian dance pop hitmakers Stargate, and in spite of everything it sounded hard as hell. Wiz Khalifa's hometown anthem was the right song at the right time, topping the Hot 100 just as the Steelers headed to the Super Bowl, and that massive hook was so powerful that it's still a little surprising that it didn't singlehandedly enable them to win the game.
