But based on Spotify traffic, her most-remembered song today is (I'm Not Your) "Superwoman" from that debut album. She put out a couple more albums in the early 90s, scoring her highest charting single with 1991's "Romantic", reaching #1 on the Billboard Hot 100 in November 1991. I don't really remember that one, but I suppose I was focused on alternative rock by that time.
After a few years out of the game, Karyn White returned with her 4th album in 2012. That same year she began a relationship with fellow R&B artist Al B. Sure!, who coincidentally enough will be coming up shortly in the '91 MusiCards checklist. They're still together according to Wikipedia, and Karyn is still at it, with live performances scheduled for the coming months.
