I'd be lost without music. I listen to music in the car everywhere I go, and listen to headphones all day at work. When I get home and have leisure time sometimes I don't even put on the TV I just put on music and relax on the couch.
I can pretty easily control my mood just by what kind of music I listen to. Sometimes if I'm sad, angry, etc I listen to sad or angry music, and other times when I'm sad or angry I listen to music that's the opposite of those emotions to pull myself out of them. I use music for inspiration, motivation, connecting with my emotions, even to express myself to others. A lot of times the right song can let a person know how you're feeling better than you could using your own words. These are all amazing things about music.
I've always been into music but never more so than I am now. I'll agree that most top-100 pop and FM radio is terrible these days (and was probably terrible when I listened to them as a kid but I didn't know any better), but there's soon much more out there if you just look for it. With the internet, Pandora and Spotify around finding new artists and expanding your musical tastes has never been easier. I have thousands of songs on my computer/iphone and a monthly subscription to spotify. Discovering new music has even sort of become a hobby for me.
I sing and play in a band too. Taught myself guitar a year ago and put together the band about 6 months ago. It's such a great outlet. As someone mentioned already, this self-righteous douche probably has zero musical skills.
