Well, that's just sad.
As a young person myself, I like blues, and jazz, and I love music that is introspective/reflexive, and thought-provoking. Actually, movie soundtracks are my fav. I don't like angry, loud, rebellion, etc. Honestly, I'd take Sinatra (or Mel Torme) over heavy metal any day.
Then again, I'm a freak.
I'm an old fart and I like it all. Even some rap I can appreciate. Some of my favorite stuff is very loud like the Mahavishnu Orchestra and the Clash I don't like it if it isn't played loud. But I love virtually any authentic music although the Chinese and Japanese is hard for me to appreciate.
Oh, and welcome aboard. My younger son just turned 21. He is mainly into Metallica.
