I thought this would be a fun idea. Towards the end of every week, I've decided to post the current Billboard Hot 100 number one single, as well as a few of the songs that were also number one on this very same week years ago.
2012: Fun Feat. Janelle Monáe- "We Are Young"
2003: 50 Cent- "In Da Club"
1997: Spice Girls- "Wannabe"
1994: Ace of Base- "The Sign"
