Yeah, good for The Weeknd. :) I feel pity for Heathens and Cold Water, which don't have chances to peak at no.1 anymore, though, moreover because Heathens is the second song by Twenty One Pilots which reached no.2 but not no.1.
They were new in the Billboard Hot 100 plus that Hello topped the chart when Stressed Out is charting. Heathens is still gaining on radio but Closer is on the top of every music mediums right now: streams, views, airplays, sales. In 2-3 weeks, Starboy has the chance to top the charts.
Yeah, it is much a forum site. It's like a site full of music knowledge. Kworb is in there too, the creator of Kworb.net and some users who update sales on every artists, that's where I got those Ariana Grande Sales.
