There are plenty of new genres & subgenres of music that have emerged in the last 40 years that you're probably not aware of or maybe never listened to before. Much in the vein of electronic, industria and hip hop. Hip hop has entire subgenres unto itself. And people making comments that hip hop requires no skill other than a laptop and a mic probably haven't spent much time listening or exploring the genre.
In fact, Rapper's Delight was cut with a backup band replicating the DJ spun breakbeats. Early DJ & rap crews were rhyming over disco and funk records which kept those from fading away into obscurity. If you like Nirvana, you can thank the disco and funk beats of the 70s for inspiring Dave Grohls drumming. Dave Grohl Inspired By Disco Drum Beats - YouTube
And plenty of hip hop/rap artists use live musicians as a way to break out creatively. The days of two turntables and microphone have long passed.
What has been terrible for pop music in general is that many of the same top artists use the same song writers and producers which leads to repetition. The overuse of autotune and you have a sameness to it. But again, like with any "genre" of music you have to be willing to dive in and find the unique stuff.
I find the excuse of being over the age of 50 for the reason for not liking certain kinds of music a bit lazy. I'm 51 and listen to just about everything and I discover new types of music and new bands almost every day w/ Spotify. It's a great time to discover new new music and new old music.
