Muse isn't usually the type of band you'd expect to see on the pop charts, but the British rock trio are starting to gain momentum with their 2012 single 'Madness.' It's interesting to see how many rock songs are crossing over as of late, also with Imagine Dragons, who are moving on up, stationed at No. 9 this week with 'It's Time.'

Way down in the tip-top spots, Maroon 5's reign with 'Daylight' has been trumped by Bruno Mars. The 'Unorthodox Jukebox' crooner's latest single 'When I Was Your Man' is number one this week. Rejoice, Hooligans!
