I never thought I liked soul .....but.....

So I just hear Harold Melvin and Blue Notes. "don't leave me this way". and cannot stop listening to the opening. It is so intoxicating. Can anyone point me to more music like this? I am talking about the smooth, gentle, drum/keys/guitar opening. makes me dizzy in a good way. I have been looking on my own and there is just so much out there. TX!
