Top 10 tracks

TOP 10 TRACKS: Katy Perry’s “Dark Horse” is in full gallop, picking up 12% to take this runaway hit kissing close to 300k and north of 2.3m RTD. Jason Derulo’s similarly fast-moving “Talk Dirty” rises four spots to #2 behind a 31% uptick. “Happy,” Pharrell Williams’ latest bindle of ear cocaine, enters the Top 10 on a 57% jump fueled in part by his visibility on the Grammy telecast. It didn’t hurt Lorde either, as both “Team” and #13 “Royals” posted week-to-week increases. Bastille’s “Pompeii” continued its climb, moving 10-6 on +15%. And Frozen’s Idina Menzel remained icy hot, reentering the Top 10 with a 10% gain.
