Billboard Top 50 Hip-Hop/R&B Songs This Week

Billboard Hip-Hop/R&B Songs is the official Hip-Hop/R&B chart in the United States released weekly (Thursday) by Billboard.
It lists the week’s most popular R&B/Hip-Hop songs, based on radio airplay audience impressions as measured by Nielsen Music, sales data as compiled by Nielsen Music and streaming activity data from online music sources tracked by Nielsen Music. Songs are defined as current if they are newly-released titles, or songs receiving widespread airplay and/or sales activity for the first time. Thoughts?
