We'll breakdown 2008, but you can relive all the Hot 100's number one hits year by year:

The year is 2008. Pop culture and politics become inseparable after Tina Fey's impersonation of Republican Vice Presidential nominee Sarah Palin on Saturday Night Live goes viral and Black Eyed Peas member Will.i.am molds then-candidate Barack Obama's campaign slogan "Yes We Can" into a celebrity-laden YouTube hit.

Obama makes history when he is elected the first black President of the United States, and the U.S. wins 111 total medals during the Summer Olympics in Beijing, which attracts 4.7 billion worldwide viewers to become the most-watched Olympic games in history. The Dark Knight Rises becomes the highest-grossing movie of the year, with actor Heath Ledger winning a posthumous Oscar for his role as The Joker. 

Meanwhile, in music, Britney Spears snags a No. 1 hit with "Womanizer" despite heavily-publicized personal issues, Rihanna continues to rake in hits with the reissue of her third studio album Good Girl Gone Bad: Reloaded, Flo Rida reveals the hypnotic power of Apple Bottom jeans and furred boots with the hit "Low," and Beyoncé's "Single Ladies (Put A Ring On It)" becomes one of the best-selling singles of all time, with a highly-imitated—and parodied—music video to boot.
