It's not AI generated music, it's AI generated noise

Old cranky people have always hated change. Using terms like proper, real and "music" (in quotes) is just meaningless elitism and gatekeeping. Anyone can make music. Nobody is entitled to live from music.

When gramophones arrived, "canned music" was not real and took jobs. Then Rock'n Roll was not real music, Punk rock was not real music, then disco was not real music, using synth was not real music,

People listen what they like.

A human being creates elevator music, bland YouTube tutorial background music, commercial jingles. None of these are perceived as creative or powerful, but we would never know how much human spirit goes into it. Maybe the creator of some terrible stomp-clap music used for a corporate presentation channeled his terrible divorce, the death of his father and his frustration at 20 years of creative failure and derivative works into it, but who would ever know? Maybe him and his close friends. It's the feeling that the music inspires in the listener that gives it value.
