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

Taylor Swift and Selena Gomez reminded the world their BFF status is as strong as ever when the pop stars posted a pair photos playing off the former’s “Out of the Woods,” the sixth and current single from her smash album, 1989.

Selena also has reason to celebrate this week, as her single “Same Old Love” climbs to No. 5 on the Billboard Hot 100, matching “Good For You” (featuring A$AP Rocky) as her highest peaking song ever on the chart.

Meanwhile, Meek Mill and rap disses resurface in 2016, with the Philadelphia native releasing a surprise mixtape, 4/4, on Saturday (Jan. 16), an expected sneak peek of the upcoming fourth installment of his Dreamchasers mixtape series. Mill also fired disses at 50 Cent, who responded by posting a series of Instagram posts, sparking a back-and-forth between the rappers on the social media platform.

4/4 also contains lines that reignite Meek Mill’s well-publicized 2015 feud with rival Drake, parodying the Canadian MC’s “Jumpman” (with Future) in his track “I’m Da Plug Freestyle.”

Future may have gotten wind of Meek’s release, because the rapper dropped his own surprise mixtape, Purple Reign, the following day (Jan. 17.) The 13-track collection, whose title and cover art font pay homage to Prince's landmark 1984 album, Purple Rain, continues the rapper's momentum from 2015. Among his chart achievements,he scored his first two Billboard 200 No. 1 albums last year, DS2 and What A Time To Be Alive, with Drake.

Plus, One Direction may have just started their “extended hiatus,” but the group’s Liam Payne is already returning to the studio. The boy band member dropped a short snippet of some rapped bars online via Instagram on Jan. 16. Despite the group’s hiatus, sources suggest Liam has no current plans to release any solo material.

Liam did, however, reveal that the hit-making boy band isn't splitting up for good, despite rumors. TMZ caught the lad in the Los Angeles airport, and he affirmed the group is not calling it quits.
