...mine has to be "Soon I'll Be Loving You" from the I Want You deluxe sessions..that singing sends chills down my spine..he starts off sort of delicate and soft and by the end of the track hes soaring and weaving through notes and patterns,,I think this was Marvin at his true genius..love Whats Goin On LP but "Soon I'll Be Loving You" is the one for me..right gotta play it now..
