Shazam

TAG, THEY'RE IT: Island's Tove Lo now has the most Shazam'd song in the USA, perhaps because we have to stay high all the time too; RCA's Mr. Probz enters the Top 5 and OVO/Warner Bros.' ILoveMakonnen hits the Top 10. David Guetta's new track is by far the week's biggest jumper, while Ariana's duet with The Weeknd, "Love Me Harder" (Republic), newly inked Columbia rapper Dej Loaf and RCA's Tinashe, among others, vault upward. Capitol's Sam Smith sees his "I'm Not the Only One" jumping #29-13. For more of what Americans are pointing their phones at (sortable by rank, artist and biggest jumps), go here. In the U.K., Jeremih's "Don't Tell 'Em" lands at #1, while Lilly Wood et al's "Prayer in C," Guetta, the BBC's all-star "God Only Knows" (credited, aptly, to Brian Wilson and Various Artists) and Pharrell's "Gust of Wind" are among the greatest gainers. To see what Brits are aiming their mobiles at, go here. Shazam and away! (10/14a)
