Where does it say that Rap music doesn’t have Melody or Melodies? The Rap that I’ve had the limited amount of time to listen to not only has melodies but very good musicians backing the artist, whether live or recorded. Key word - artist. Even in rap itself the phrase ’the beat(s)’ is actually a misnomer. In rap a beat is a construct of many different musical components designed to hold a groove. Whether it be a melodic ’love’ rap or a rap dance song, not just a (computer?) driven drum beat.
Although rap is not a favorite of mine I have been fortunate enough to has enjoyed some of the ’club bangers’ as the kids have called them over the years of rappers music with music samples of some of the best music ever. I just had to respond to some of the absolutism or is it elitism here.
The disintegration of speech and language depth in lyrics is not a fact about "taste" but about mind conditioning in an uneducated controlled social fabric..
And about vibration(s)? I’ve already made lengthy responses to that subject, here on Audiogon. And Rick Beato, I wholeheartedly agree with you on him, I've responded to him once that I was not in agreement with some of his comments
