Does anyone else think recently mainstream music has changed to something almost unbearable?

Chances are if it came after the 80's I've never heard it. (I'm not even 15 years old) I love the older stuff (anything from 80's rock/metal to classical music) and I can't stand Justin Beiber...Ugh, gag me! lol! I listen to stuff my parents, grand parents and great grand parents listened to. Music used to have meaning, melody, not just people talking with computerized instruments, and auto-tuned to the moon...
