I disagree strongly, but I can relate to your feeling. When the mumble/trap/emo rappers like Lil Pump got big, I didn't understand it, and I still don't. It was terrible, and I thought maybe I'd gotten old and I didn't "get" new music. However, then I heard Kevin Abstract, who's wonderful, and I realized the mumble/trap thing was just a bad, trashy era, just like hair metal in the 80s, nu metal and teen pop in the 90s, etc.

There's a lot of amazing music happening right now, but I think one thing that's hard to adjust to is that rock music is now basically a niche genre. It was a major mainstream genre from the 50s through the 00s, but now it's more of a specialty thing. This means to really get today's music, you almost have to adapt to electronic or hip hop music. However, there's still great rock music, especially in the metal and indie worlds. One interesting thing about rock becoming niche, is that it gives more of a spotlight to more challenging subgenres. Right now extreme metal bands like Behemoth and Gojira have basically achieved rockstar status, which was once unthinkable. There are some really cool hardcore and crust punk bands going right now, like Touché Amoré, High Tension, Harm's Way, and Oathbreaker.

The other thing is, while there is some really trashy hip hop music right now, there's also a lot of amazing stuff. Tyler, the Creator is amazingly successful, which is really exciting because in the past he'd simply been too challenging and weird for the mainstream. I also see really experimental groups from the past who fused electronic and hip hop music, like Massive Attack and MIA, having a big influence on major artists.

I'm 32, and I'll always love the rock bands I grew up with, like The Libertines. But there's a lot of exciting new stuff, you just have to know where to look.

Also, it's 2021. It's ridiculous to already discount the 2020s. Even the concept of putting music into decades is silly - music from 1970 obviously has more in common with 1969 than 1979.
