Katy Perry killed it last Friday in our 'Sound Off' battle against Big Time Rush. Mrs. Russell Brand had more than 60% of the votes for her single 'The One That Got Away,' trumping 'Music Sounds Better With U' by the BTR boys. Now, we are matching Perry's midtempo tune versus Britney Spears' latest release, 'Criminal.'

'The One That Got Away' and 'Criminal' are both slower-paced tunes for the pop goddesses, but Katy and Britney produced infectious beats and catchy hooks with their newest singles, both of which are about relationships gone wrong (in Britney's case, a more 'Toxic' romance). Cast your vote for which either 'The One That Got Away' or 'Criminal' and we'll let you know which songstress comes out on top tomorrow!
