I am constantly buying new music, almost none of it is overproduced, and I never hear autotune (and I don't really mind autotune that much, given I don't hear it much).

It's dead simple - I simply directly from artists, usually on Bandcamp.

Commercial new music hasn't changed in decades: autotune has been all over everything since Cher's 1998 hit Believe.

But actual musicians are going strong and doing new things. AI is not going make the slightest dent in that.
