"you don't like the music that I LIKED when I was growing up, which means you have bad taste!"

I dunno man, I grew up in the 90's and I definitely question the musical taste of my younger self. And there are plenty of artists whom I can appreciate their significance, but I would never just sit down and listen to. Bob Marley is one. Led Zeppelin is another. Jimi Hendrix can go one way or the other.

Times change, technology changes, tastes change, and that doesn't mean anyone is wrong because they don't like the same things you do.
