October 9, 2012 It's been an amazing career so far for Rihanna. She broke into the music scene in 2005 and now has managed to find herself in the #1 position on Billboards Pop Songs chart.
May 13, 2011 Katy Perry's Teenage Dream album has produced 4 singles that have each reached the #1 spot on the Billboard Hot 100 chart. Any artist that releases music dreams of having a #1 song, but its happened to Katy Perry 4 times off the same album! With all of those #1 songs, Katy Perry has spent the last year inside the top 10 on the Billboard Hot 100 chart, marking the first time ever an artist has done that.
