Shazam

TAG, THEY'RE IT: Jason Aldean's "Burnin' It Down" (Broken Bow) has been melting the iTunes singles chart for a while, so it's no surprise to see he's the biggest jumper on Shazam's USA Top 100. But Capitol's Mary Lambert leaps a startling 81 spots with the candid, high-spirited "Secrets." Big gainers outside the Top 5 include Capitol's 5 Seconds of Summer with "Amnesia," Dot/BMLG's Maddie & Tae with "Girl in a Country Song," Interscope's Jamie N Commons & X Ambassadors with "Jungle" and Republic's Weezer with "Back to the Shack." For more of what Americans are pointing their phones at (sortable by artist, rank or increase) go here. On the U.K. chart, meanwhile, we note major progress by Hozier (on Island over there; on Columbia in the U.S.) with "Take Me to Church." (7/29a)
