VIEW THE REAL-TIME CHARTS: TRENDING 140 | EMERGING ARTISTS

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

Because the fans demanded it, we kick things off by reviewing all the success Fifth Harmony has had on the Realtime charts, particularly with the Kid Ink featured track “Worth It.” The title spends its second week at No. 2 on the weekly Top Tracks chart after topping the Trending 140 multiple times. The group, which was originally formed on the second season of X Factor USA, has had three other tracks top the Trending 140 from the group’s debut album Reflection, including “Boss,” “Sledgehammer” and “Like Mariah.” This week on the Hot 100, “Worth It” ascends 18-15 in its 17th week on the chart.

Next, another X Factor-formed group. Little Mix earned their first hit on the Twitter charts with “Black Magic,” which reached No. 1 on the Trending 140 and subsequently No. 3 on the weekly summation. “Magic” got props on Twitter from Tyler Oakley, Cher Lloyd and of course, Simon Cowell.

Then, new releases from two of pop’s biggest stars impact the Trending 140. First is “Nightmare” by Miley Cyrus, a leaked track that surfaced online last week and reached No. 1 on the Trending 140. It’s still unclear whether or not this song is tied to a particular project: sources at E! suggest its a leaked demo she sang for someone else. Then, Selena Gomez releases a teaser on Instagram for a new track “Good For You,” which is set to drop on June 22.

Last, “Fight Song” by Rachel Platten tops the chart after reaching No. 1 on iTunes following her performance of the track alongside Taylor Swift during a recent 1989 tour stop in Philadelphia. This breakout his from the 33 year odl singer is from her EP of the same name that was out in May.

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.
