In general I think people who play an instrument or sing etc. are more into music than someone who doesn't play/sing, I think once you have the music bug you always have it, it's a bit of an addiction. I listen to music everyday because I love it, on my iPod, on my PC, on the Hi-Fi, I listen to it every night laying in bed before I got to sleep, it's a way of life. Most people listen to music and enjoy but probably not as much as someone who is totally passionate about it like a lot of people who play/sing. Different strokes for different folks guess !!
