Rihanna & The Janoskians: Real-Time Twitter Chart Rewind Ep. 40

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

Meghan Trainor gains a new No. 1 on the Trending 140 with her new single, "Dear Future Husband." She debuted the video on March 16, causing the track to race to the top of the chart. "Husband" becomes Trainor's third chart-topper, following the monster hit "All About That Bass" and "Lips Are Movin'."

Meanwhile, Snoop Dogg recruited familiar collaborators Pharrell and Charlie Wilson for "Peaches N Cream," which dashed to No. 1 on the Trending 140 on March 10. "Peaches" earned an extra boost when Snoop's performed the track during his appearance on the season finale of TV's Empire on March 18, triggering the track's return to No. 1 the following day.

In addition to "Peaches," Pharrell grabbed another No. 1, though under different circumstances. After a jury found Pharrell and Robin Thicke guilty of copyright infringement for their 2013 smash "Blurred Lines," discussion about the song skyrocketed, and consequently launched the track to No. 1 on the Trending 140.

The biggest story of the week, however, was Kendrick Lamar's early release of To Pimp A Butterfly. In addition to setting a one-day Spotify streaming record, the album dominated the Trending 140. Hours after the album's unexpected release on March 15, all of Butterfly's 16 tracks simultaneously placed on the chart, and at one point, Lamar controlled the chart's top six spots. With the achievement, Butterfly's release parallels the initial results of other major albums, including Taylor Swift's 1989, One Direction's FOUR and Drake's If You're Reading This, It's Too Late
