When rap came out 30 years ago I thought it was just a fad

"doesn’t want or need" By Jove! I think he’s got it!

bdp24,
I saw the "60 minutes" segment about the composer/performer of "Hamilton." Yes, he's a very talented young man.
He said that he wrote the music to be sung in the Rap style; that's his interpretation. You don't have to like it, in fact I don't think I could sit thru an entire Rap musical to be honest.

This Broadway musical is another example of Rap that is here to stay and is not part of the "thug" genre. Earlier, I cited the Roots as an outstanding band with a Jazz, Funk, R&B sound using Rap and Soul styles to perform their vocals.

I dislike the Rap I hear today and the message it's sending to the younger generation, but there will be diversity within the genre in the future. And if you don't like it, that's fine; we all have our own unique preferences. This isn't a forum to convince you to like Rap.

Like others have stated, modern commercial rap is quite different from rap 20-30 yrs ago. What once was a creative platform has turned into an homogenized, watered down shell of itself. Same could be said of the convential "pop" single which craftwise peaked in the 70s.Same for aggressive hard rock: the pinnacle of the art form was in the 70s. Progressive rock: 70s. Reggae: 70s. Psychedelic: 60s. Glad I went to school years ago as there is nothing new today. 

"certain kind of so called music lovers"--but, of course, you don't mean anyone here, right? 

No accountability = no credibility.
