To most people, though, it all sounds the same. One reason for that is, especially at first, most rap was produced by a tiny handful of producers.
Yes, 25 years ago Ed. Done any critical listening lately, meaning the last 15 years? Of course it sounds the same to you in the same way the blues sounds the same, old 50's rock and roll sounds the same, classic country sounds the same. What? Whaddya you mean Bob? Johnny Cash sounds nothing like Willie Nelson, BB King sounds nothing like Albert King, Buddy Holly sounds nothing like Chuck Berry, man!!
Of course they don't because you grew up with it, knew all the players, knew all the band members, watched all the TV shows, etc. etc. You were young, all your friends were into all the same stuff, it seeped into your bones, it was part of the culture you grew up in. That's why people in their 40's now have little clue about the artists I just mentioned. They're pretty much rap/EDM fans and can list all the same things about their favorite artists. To them we're just a couple of old farts who don't have a clue.
Anyway, I agree with your point about shyster lawyers.
