Top 10 tracks

TOP 10 TRACKS: Lorde’s “Royals” not only appears to have a stranglehold on #1, it also continues to increase in sales week over week; the latest uptick is 5%, as the track once again crossed the 300k threshold. The other big hand—three of a kind—is held by Katy Perry, as a third Prism track, “Walking on Air,” debuts on the big board. Drake’s “Hold On, We're Going Home” returns to the Top 10 after dropping to #13. But get this—it’s up a whopping 64%. These three are bucking a disturbing trend.
