Top 10 tracks

TOP 10 TRACKS: Iggy Azalea is on fire. “Fancy” broke 300k and leapfrogged "Problem" to emphatically take over the top spot, so the Aussie rapper and her gal pal Ariana Grande have cause to celebrate as they tower over the field. Practically every Top 10 track was up over the previous week, Ed Sheeran returned to the big board with his Pharrell-powered “Sing,” Magic! jumped #15-9 and the Miranda-Carrie country-diva duet made a smashing debut.

1. Iggy Azalea f/Charlie XCX, “Fancy” – 336k
2. Ariana Grande f/Iggy Azalea, “Problem” – 284k
3. Nico & Vinz, “Am I Wrong” – 156k
4. John Legend, “All of Me” – 147k
5. DJ Snake & Lil Jon, “Turn Down for What” – 137k
6. Pharrell Williams, “Happy” – 134k
7. Jason Derulo f/Snoop Dogg, “Wiggle” – 124k
8. Ed Sheeran, “Sing” – 114k
9. Magic!, “Rude” – 112k
10. Miranda Lambert & Carrie Underwood, “Somethin’ Bad” – 85k

Looks like OneRepublic has another one, as “Love Runs Out,” the follow-up to the band’s humongous “Counting Stars,” moved #38-11 with 93k for a +128%. (5/29a)
