TAG, THEY'RE IT: SHAZAM'S BIGGEST MOVERS

New music from Geffen's Avicii, 222/Interscope's Maroon 5 and ByStorm/RCA's Miguel lead the biggest gainers on Shazam's USA Top 100 this week, while Def Jam's Logic moves #16-3 as its post-VMAs liftoff continues. Another breakout from Insecure, Roman Gianarthur's slow jam "Real Love, No Shade" (Wondaland) and NBA hype jam "Ready and Rough" from Dominic Glover, Gary Crockett and Jason Glover round out the Top 5 jumpers.

Astute readers will recall that both Maroon and Miguel are managed by Jordan Feldstein's CAM, or as it shall henceforth be known, Sha-CAM.

Among other acts making strides on the USA chart: Astralwerks/Capitol's Halsey with "Bad at Love" and RCA Nashville's country chart-toppers Old Dominion with "No Such Thing as a Broken Heart."

Avicii is the biggest gainer on the U.K. rundown as well, followed by Anna Straker with the beguiling electro-pop workout "Serious" (Youthemic), which got a boost after a BBC Music Introducing feature. Who else is rising on that side of the pond? Among others: Naughty Boy, Maroon, Logic, Michael Kiwanuka and the late soul/dance siren Viola Wills, whose "Gonna Get Along Without You Now" got a boost from a Talk Talk advert.
