I like it. I listen to classical music every morning when I'm getting ready for work.
I played violin in orchestra from 4th grade through some time in high school and took piano lessons for about seven or eight years. Somewhere along the way I picked up a guitar and went the other direction. I think it had something to do with the instant satisfaction of bustin' some heavy grooves with just a few other musicians vs. whatever it was I got being part of a large orchestra. Classical music is very technical and only works if everybody is spot on. As a player there is little or no room for improvisation and it can become very tedious and boring. Besides, no hot chicks ever jumped up on stage when I was playing violin.
I still have a number of guitars (amps and piles of other related stuff I haven't used in years), but no violins and no pianos. I'd love to get back to playing piano and maybe some other stringed instrument, but I hardly ever have time to pick up a guitar anymore.
I listen to all kinds of stuff (even some rap and hip-hop), but if I have to play it, I prefer rock, blues & bluegrass. I do believe that if you are a musician or want to be one, listening to classical music is good for you. Rap, which I think of as people talking really fast, and occasionally rhyming, can be entertaining, but by itself seems to have little musical value.
