So what was happening on the Real-Time Charts this week?

Kanye West was on top of the Trending 140 twice this past week. He first topped the chart with his new song "Wolves" featuring Vic Mensa and Sia, which he debuted at his Adidas NYFW show. It was streamed online on Feb. 12. 'Ye performed the song later, during the Saturday Night Live 40th Anniversary Special on Sunday, Feb. 15.

Also dominating the chart is Drake, who debuted a surprise album, If You're Reading This Its Too Late, at midnight on Friday, Feb. 13. By Wednesday, Feb. 18, six of the album's 17 tracks had charted on the Trending 140. By Friday, Feb. 20, 15 of the 17 tracks had hit the chart; that's because there have been more than 1.5 million mentions of the album and its songs in just six hours after its release.

The same day as Drake's release, Taylor Swift dropped the official music video for "Style," effectively barring any of the tracks off If You're Reading This Its Too Late from obtaining the No. 1 spot.

Ariana Grande topped the Trending 140 with her single "One Last Time" twice during the week. Once after performing it at halftime during the NBA All Star Game on Saturday, Feb. 14, and then again the next day (Feb. 15) after the debut of its official music video on Vevo. It's the fifth time a video release or TV performance has pushed "One Last Time" to No. 1 on our chart.

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.
