I've posted this before.
I can't tell you how much I enjoy the early-1970s Stevie Wonder. I loved it as a child. As a middle-aged guy I still love it. Genuine talented musicians, jamming to funky tunes. Maybe Your Baby is so so cool. (Every single voice is Stevie. Featuring Ray Parker doing the wicked guitar solo!)
Stevie's problem since the "Ebony and Ivory" disaster I think started because he quit playing real drums and started programming drum machines and started using lousy-ass samples. I also think it was the time he started to take the "Stevie Wonder is a musical genius" message too seriously.
