My mom loves her some Chaka. She went to a Chaka Khan concert back in the 80s and still has the pictures. By the looks of it and the stories I heard Chaka could put on a show! I like her well enough too along with the other "scream queens" - Aretha, Tina (fav), and Patti. Chaka is one of the few people I will agree covered a Prince song better than the original ("I Feel For You"). TLC also did a good job on "If I Was Your Girlfriend" from their CrazySexyCool album.
Speaking of covers, Beyonce does a cover of Anita Baker's "Sweet Love" in a medley of her own songs here:
Any Musiq Soulchild fans? I know he's not really considered classic R&B but I enjoy listening to his music.
I liked his first album a lot. 2nd album I liked too. After that I lost interest....didn't really like SoulStar, then he kind've went away and I forgot about him, and I haven't heard any new music from him in a long time. Have no idea what he's done recently, the last thing I remember was B.U.D.D.Y.
Girl Next Door, Love, Just Friends, and Don't Change all got heavy play from me at one point.
