Maroon 5 are no longer leading PopCrush's Top 20 Songs for the week of Aug. 6, 2012, but they've been bumped to the No. 2 spot by a worthy competitor -- Katy Perry. Her tune 'Wide Awake,' which is one of our Top Songs of 2012, is now the No. 1 track on our Top 20 countdown.

What other tracks are charting this week? David Guetta is making his Top 20 debut with his single 'Titanium,' which features an incredible vocal performance from Sia. Additionally, Pink's 'Blow Me (One Last Kiss)' has moved from No. 8 to No. 4 this week, while One Direction fall back a few to the No. 10 notch on the countdown.
