Katy Perry's "Dark Horse" continues to reign at No. 1 -- though it has a significant drop in sales. The song sold 291,000 downloads in the most recent tracking week, down 22%. The sales erosion is owed to how the song saw a big 27% gain a week ago, following Perry's performance on the January 26 Grammy Awards. Without the Awards show exposure this week, the song's sales naturally came back down.
Pharrell's Oscar-nominated "Happy," meanwhile, continues to gain, as it climbs 3-2 with 252,000 (up 15%).
Jason Derulo's "Talk Dirty," featuring 2 Chainz, is pushed back 2-3 despite a gain of 3%. It sold 242,000 last week.
Passenger's "Let Her Go" steps 5-4 with 182,000 (up 3%). A Great Big World & Christina Aguilera's "Say Something" is up 6-5 with 171,000 (up 12%).
Idina Menzel's "Let It Go" flies 16-6 with 138,000 (up 28%) -- the song's second-largest sales week. It only sold more over Christmas week, when it shifted 153,000 downloads.
Bastille's "Pompeii" is up two rungs to No. 7 with 131,000 (down 6%), Pitbull's "Timber," featuring Ke$ha, is steady at No. 8 with 130,000 (down 9%) and Aloe Blacc's "The Man" rises 13-9 with 125,000 (down 3%). Lorde's "Team" rounds out the top 10, as it ascends 12-10 with 113,000 (down 13%).
