Real music should be able to move you. To make you feel the emotion that the artist felt when making the song. To me this is true art. Not one of those "mainstream pop" groups but artists who make music not for the money, but because they truly enjoy what they are doing. Artists like Paul Oakenfield, Carl Cox, and Robert Miles to name a few, fit that category. Sure they tour, and are relatively the "big" names in the trance scene, but they haven't lost sight of what music is to them... their outlet to express what feelings they have inside. If not for them, I would have surely have gone mad by now.
