I have a very special and secrete perspective on rnb cos I never get any action whatsoever. That changes the emotional tenor of songs about shagging. Fills them with a deep melancholy charge. This is probably the same perspective that informed Burial sampling RnB. Compare how UK garage producers in designer clothes popping bubbly on the white house lawn sampled RnB.
I didn't "get" r&b until I was in my 20s because I didn't understand truly the emotions you find in r&b. Like I could tell a song was horny or heartbroken or whatever but I couldn't relate. Well, I don't think relate is the right word - because it's a genre based on performance and demonstration, r&b is all outsize emotions that you can insert yourself into, whether its sexier than sex itself or sadder than sadness itself etc.
