They were paired up with Hip Hop/Rap formally, but this chart will focus solemnly on R&B music. Billboard stated that “R&B Songs” will look at the same airplay and sales hybrid formula to rank the week’s top R&B-only titles. Who’s at the top of the list? None other than Rihanna! "Rihanna shuffles from No. 66 under the former Hot R&B/Hip-Hop Songs methodology all the way to No. 1 with "Diamonds," aided by crossover pop airplay of the track as well as strong digital sales (No. 1 on R&B/Hip-Hop Digital Songs). "Diamonds" also tops the inaugural R&B Songs tally," Billboard said. They’re also factoring in streaming data as well, with digital downloading sales.
