Poll: MY Music Challenge: Katy Perry vs. Kodaline

Voting ends at 9pm on 4/21. Until then, keep voting!  

Champion: Katy Perry 'Birthday'

Katy Perry had a break out hit with her song "I Kissed A Girl," but it was her second album, Teenage Dreams, that propelled her into a worldwide popstar. Five singles from the album hit the top of the charts, a feat only replicated by Micheal Jackson's Bad album. 

Challenger: Kodaline 'All I Want'

Formerly known as 21 Demands, Stephan, Vinny, Jason and Mark make up Kodaline, a band from Dublin, Ireland. Songs from their debut album, In A Perfect World, have been featured on episodes of "Grey's Anatomy" and "The Vampire Diaries."
