Summary Current artists overdub and remix Marley tunes. Not a bad idea if it's done right.
Duets connote songs being sung together.
These are overdubs. True to the original, subtle, understated. Badu's voice is a beautiful compliment and she doesn't go overboard trying to overshadow Marley. Not as awful as you'd expect, but still offers nothing special over the original. I think Marley would team up with if he were still alive.
