Patrick Stump beat out Britney Spears in our 'Sound Off' yesterday, raking in more than 80% of the votes. Congrats to Patrick and his tune 'This City' for dominating! Today, our 'Sound Off' series gets a little more personal, as we pair Patrick Stump's Lupe Fiasco-featured track 'This City' versus his pals in the Gym Class Heroes' collabo track with Adam Levine, 'Stereo Hearts.'

A few years back, Stump lent his signature vocals to the Gym Class Heroes' hit song 'Cupid's Chokehold,' so this win could be bittersweet for both parties. However, there's nothing wrong with a little friendly competition, right? Both 'This City' and 'Stereo Hearts' have been ruling the airwaves the past few months, so it will be interesting to see who wins this one! Cast your vote for either Patrick Stump's 'This City' or Gym Class Heroes' 'Stereo Hearts' below and we'll let you know who is the champ tomorrow.

Rules of ‘Sound Off’:
There’s only one rule for our ‘Sound Off’ series: If a song remains the reigning champ for five straight days, it is retired to PopCrush’s ‘Sound Off’ Hall of Fame. With tons of great tracks coming out everyday day, we have to give other artists a chance to win!
