Not every "real" band I listen to really has chord changes or melodies, or they aren't a focal point of the band. I mean, look at Sunn; that's definitely not noise, but you can't really hum one of their songs, and though they have chord changes they don't really make a difference to the listener; it's all about how powerful and compelling the sound is. I listen to music because it's interesting to listen or compelling... that's how I listen to noise as well.
