Oh wow indeed, after some research it looks quite trivial indeed!
Meanwhile, the songs need to be DRM-free to be exported that way. In which case, I am not sure why someone would use iTunes rather than Bandcamp/etc.
Because they make it cheaper? Then, are you even supporting the artist through iTunes?
Otherwise if it’s the same price or lower, rather get the music file directly from the artist (via Bandcamp or their own thing).
