When I was a kid I listened to Metallica, and I thought I was very cultured because I listened to music from 20 years ago. But to my surprise, kids today aren't listening to 50 Cent, they're still listening to Metallica, now 40 years old.

IMO one of the reasons for the timelessness of what is now considered classic metal music is because it has similarities to classical music in terms of scale, structure, and technique. One of my favorite main stream metal albums is still Master of Puppets 🤘🤘🤘
They should go deeper
Soundgarden
Alice-in-Chains
Pearl Jam
Limp Bizkit >>>
Wait til you hear Testament. First 2 albums. Every song but one is better than any Metallica song.
