The Wanted have done it again! The quintet from the U.K. have dominated PopCrush's Sound Off for the second week in a row with their single 'Glad Your Came,' taking out Madonna's new single 'Give Me All Your Luvin'' in the most recent battle. Now, the Wanted will take on a new competitor in the form of Katy Perry and her newly released single 'Part of Me,' which she debuted at the 2012 Grammys

On 'Glad You Came,' which is growing into a massive hit in the States, the Wanted guys harmonize about a budding romance over a groovable Eurodance-inspired beat. 'Part of Me,' on the other hand, is a self-empowering, uptempo anthem about never letting a romance change who you are. It's definitely a kiss off song to Russell Brand, and you can really tell the words hold a lot of meaning for Katy.

So, which song has roped you in? Vote for either the Wanted's 'Glad You Came' or Katy Perry's 'Part of Me' below -- the poll will remain open until Tuesday, Feb. 21 at 8AM EST.
