I used to have this program on my old Mac called SoundEdit. I had version 16, I believe. It was a super-simple program. I'm sure it could easily fit on any phone now, but I had loads of fun with it, making some pretty wild noise, sort of in the vein of Autechre, although I hadn't heard them at the time. I still have a bunch of the tapes I made. The sounds that thing could churn out were absolutely wicked. Its best feature was its bender, which I believe made it possible to put unlimited points in wave to bend it with. It was noise, I suppose, but it was still structured sound, and I liked to hear it, so that was good enough for me.
Anyhow, the point is that, call it music, call it noise, call it sound pollution, I don't care. If I like to listen to it, I like to listen to it. To me, it's all just where you find it. A rose by any other name and all that.
