Are you ready for Katy's continuation of her perfect storm? The Prism singer is still flying high at the top of the Billboard Hot 100 chart, due to the success of her Juicy J-assisted track about working her dark magic skills, "Dark Horse". We called it last week, and it looks like we're right: the song is strong enough to stay at #1 yet again for another week. Stealing the number 2 spot on the Hot 100 is Beyonce with "Drunk In Love", featuring hubby Jay-Z where they sing about, well, being drunk in love with each other. Pitbull & Ke$ha's jam "Timber" has 'gone down' the charts and taken the no.3 spot, while a surprising chart-climber has risen to number four: Jason Derulo ft. 2 Chainz with "Talk Dirty". Finishing off the top 5 on the Billboard Hot 100 chart is OneRepublic's "Counting Stars" off their album Native, which isn't seeming to go away anytime soon.
