Patrick Stump vs. David Guetta – Sound Off
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.'
