In the first place, so much of the aesthetic is based on gangster culture. Black gangster culture specifically. Based off of the actual real problem of black violent gang culture . How can that be considered good in any way?. And the music itself is low class, simplistic and has no real melody. i don't know why anyone likes it to be honest.
And White or Asian people copying it are worshipping black gangster culture because so much of hiphop and rap is based around that. Just look at the lyrics and music videos and what the "singers" wear and how they conduct themselves. All the tattoos , too many metal piercings, stupid amounts of jewelry (again , its based off of materialistic gang culture) just all around uglyness , rude gestures and behaviors, trashy . In general its all just vulgar.
And why is something that was invented decades ago always promoted like its "cool and modern"?
I agree with a lot of that, and rap has never been my favorite (most of my life I never listened to it at all), but not all rap is gangster rap. I've found mixes of more positive-messaged rap that I listen to occasional; great for when you're working, working out, or running, and the like.
And, yeah, it's probably more simplistic than many other music styles, but it can still have some interesting rhythm and such. A bunch of it doesn't though. There's tons of trash rap, tons of degenerate rap, tons of violence inspired rap. No argument here.
I do like to hear other cultures' takes on things, and there's some fun Asian rap but, yeah, it's also frustrating to see people latch on to some of the stupider cultural trends. Why go out of your way to copy trash, when we have enough cultural problems?
I mean, to be fair, you could say the same for most of that when it comes to rock and roll, punk, metal, and so many more. Hair metal was hilarious. Popular music has had elements of degeneracy and immorality for ages. You just have to pick and choose what you like.
Because culture stopped in the 90's-00's, and has only been decaying since. :(
Its the lowest form of music, simply because it requires no instruments or even really rhythm. Just the ability to write words that vaguely flow. With that low barrier of entry, it'll have the largest flood of actual garbage.
Worse, because the bar is so low people will overestimate their ability and then upload it for the world. Meaning the amount of garbage you can actually find is even higher, while the "garbage rock" guys aren't recording themselves stumbling over guitar strings because its obvious that they are failing.
Low barrier of entry and the fact that we are probably in the middle of its popularity peak makes it so we see all the trash. Nobody remembers the trash from the 70s and 80s because nobody re-releases the crap on best of albums.
