Not sure if OP is trolling or serious, either way, an argument could be made that Chuck ain't the easiest listen, particularly if you didn't grow up on him. Interestingly enough, when I look back on it , Chuck got a lot of memorable lines and a bunch of PE hooks are so ingrained into my consciousness that I forget where they came from, so he definitely left a mark. I remember as a kid 8-9-10 years old saying random shyt like "the rhythm, the rhythm", "bass in ya face", "don't believe the hype (eeeeyaaahhh)", I'd be quick to say "I can't do nuthin for you man" lol I know it may sound corny but literally most of that shyt just magically stuck with you. Truth be told, Chuck coined a lot of phrases and lingo, and don't get me started on Flav.
Speaking from a technical standpoint though, rap evolved so much during the 90's that listening to somebody like Chuck D for a lot of young cats is like watching black and white TV, so I get it. Even with that said, you still have to respect Chuck's voice, his message and his command.
