So what happened on the Real-Time Charts this week?

In a twist, the biggest music beef of the past week wasn’t Nicki Minaj and Taylor Swift’s back-and-forth stemming from the MTV Video Music Awards. Instead, Minaj’s boyfriend, rapper Meek Mill scoops up that honor for his tussle with Drake, who he called out for allegedly using ghostwriters for his raps.

After a few days of silence, Drake roared back with his answer, the diss track "Charged Up," which the Toronto rapper premiered on his Beats 1 radio show, OVO Sound. The cut raced to No. 1 on the Billboard + Twitter Trending 140, and performed well throughout the weekend.

But Drake wasn't done yet.

Four days later (July 29), Drake dropped a second diss song, "Back to Back Freestyle"--conveniently after Minaj and Mill performed on their Toronto stop of The Pinkprint tour. Like "Charged Up," Drake's second creation bounded straight to the top of the Trending 140.

On a happier note for Meek Mill, this week also featured the release of his music video "All Eyes on You," a collaboration with Minaj and Chris Brown. The anticipated video shows the couple enjoying some intimate, playful moments. Their star power and cuteness pushed "All Eyes on You" directly to No. 1 on the Trending 140.

Meanwhile, rising R&B star Kehlani debuted the music video for her pairing with Chance the Rapper, "The Way." The cut, from the singer’s album, You Should Be Here, flew to the top of the Trending 140 with help from the black-and-white clip, sporting some sensual chemistry between the Oakland native and the rapper.

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.
