R&B Hits That Never Made Billboard's Pop Top 40

My latest Spotify playlist focuses mostly on an era of Chart action that always fascinated me.  R&B Hits that never made Billboard's Pop Top 40.  And the era I'm talking about, which is heavily represented in this playlist, is the first half of the 80's.  While many big R&B hits crossed over to Pop in the 70's, that changed in the early 80's.  Some of the most memorable songs from that era, which are remembered today, like "Between the Sheets", "Juicy Fruit", "Square Biz", "If You Think You're Lonely Now", never hit the Pop Top 40.  A lot of #1 R&B hits never crossed over, which was something that didn't happen much in the 70's.  

My own feeling is that as CHR began to take over the airwaves in the early 80's, R&B hits were getting left out.  CHR started to play more Pop, Rock and AC songs.  And R&B songs that didn't fit into those genres got left behind.  

So, here's a Spotify playlist of the R&B hits that didn't cross over.
