Hosted by Billboard's Joe Levy, you can watch episode 9, which features Jessie J and Troye Sivan.
So what was happening on the Real-Time Charts this week?
Troye Sivan's "Happy Little Pill" reached the No. 1 slot on the Trending 140 as soon as it was available on Friday, July 25. The 19-year-old's TRXYE single was also the sixth most talked about on Twitter last week.
