Why don't most young people listen to good music anymore?

I'm 17 but people find it weird that I listen to old bands and old music such as Gun N' Roses, Thin Lizzy, Rolling Stones, Green Day and Moody Blues (the bands with real talents). Why are most people obsessed with clubbing, raving, rapping, R&B music. Don't they know that these so-called "artists" dont have any real talent and that they go to a studio where their voices are auto tuned, altered to make them sound good, for example I heard Fegie in a music video and then again on stage and she sounded terrible on stage. And it's not even real music most of it is made with electronic equipment and not real instruments like guitars, violins, pianos. What are your thoughts on this?
