Shazam Top 100

A MAP TO THE APP: A Great Big World (Black Magnetic/Epic) tops the Shazam Top 100 Tag Chart this week (up from #2 last week), as folks continue to point their phones at their car radios and other audio sources to find out who sings that "Say Something" song. In other Shazam news, "Team" from Lava/Republic's Lorde moves up six spots to #4, Katy Perry's "Dark Horse" (Capitol) zooms #21-9 and Harvest/CMG's Banks (about whom you might've read in this very Mill) takes the week's most massive leap, #113-22, powered by a Victoria's Secret ad. Other jumpers include two Republic acts, Crossover kid SoMo (#60-47) and songstress Colbie Caillat (#98-71). Shazam new releases, meanwhile—featuring two by Beyoncé—can be found here. (12/17p)
