Britney Spears Surges Up Trending 140 After Auto-Tune-Free 'Alien' Session Leaks: Listen

Last week someone leaked a version of Britney Spears' "Alien," from her 2013 album, "Britney Jean." The leak caused commotion on social media for its lack of "vocal affects."  It entered the Trending 140 at No. 10, then climbed to No. 2.

After One Direction's Zayn Malik shouted out producer Naughty Boy for his music video to "Home" (which is shot from a dog's point of view), the song shot to No. 1 on the Trending 140.

The Trending 140 chart measures the acceleration of conversation around artists and their music, while the Emerging Artists chart measures the volume of tweets around new artists and their songs.
