Why be puzzled? Just lie back, relax, and chill out.
It's always good to have diversity. Personally I like the grooves and fat chords in this semi-genre, though I don't really think it's anything new - you can find similar sounds in 70's R&B ... Donnie Hathaway, Stevie Wonder in his early 20's, and prototypical early 70's jazz fusion on the Blue Note Records label.
