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.
