Patrick Stump pretty much crushed Andy Grammer's 'Keep Your Head Up' in yesterday's 'Sound Off' competition, winning more than 96% of the fan votes for his Lupe Fiasco-featured track 'This City.' Now, the team at PopCrush is pitting the Patrick Stump tune versus David Guetta and Usher's collaborative song 'Without You.'

Both 'This City' and 'Without You' are feel-good tunes, with Guetta's leaning more towards the fist-pumping club scene and Stump's boasting an anthemic hybrid sound that fuses R&B, pop and electronica. It's up to the fans to see which song comes out on top, so cast your votes for either 'Without You' or 'This City' and we'll let you know who the champ is next Monday!

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!
