Top 10 tracks

TOP 10 TRACKS: Katy Perry’s “Dark Horse” is now massive, logging the highest weekly sales total of 2014 on a 27% increase, and driving the track to 2.7m. Jason Derulo’s “Talk Dirty” (+21%) and Pharrell Williams’ “Happy” (+17%) are exploding as well, the latter artist being lifted by his star turn on the Grammys. Indeed, the Grammy spike was in full effect last week for performers and winners alike, providing the previously waning “Radioactive” (+239%) and “Royals” (+33%) with victory laps, and catapulting Bey and J’s “Drunk in Love” (+94%) into the thick of the action, while Passenger’s “Let Her Go”(+51%) made a late charge during and after last Sunday’s Super Bowl. A Great Big World’s “Say Something” (+4) brings the total of TV-fueled hits on the leaderboard to seven.
