A lot of the music in the Spotify 'easy listening' or instrumental music sections is not AI but it's made by people who purposefully are as mentioned 'ghost writers' of a sort. Spotify will pay an upfront sum to these artists and they just slam out instrumental content. Things like instrumental jazz or easy listening piano or 'relaxing ambient massage' music. It's sort of "work for hire" for the artist and that certainly has appeal.

These artists use different names and often can have a few different names for their ghost 'artists.'

They get paid up front to slog out hours of these instrumental tracks and since Spotify has already paid them, spotify pushes their "ghost artists' instrumental tunes up certain playlists and gets to use the content they have already paid for instead of paying a $.004 stream royalty.

People pull up their spotify in the massage studio or the dentist lobby and click on "easy listening piano" or "lobby music" and off to the races. No one in the optometrist's office looks at a 'relaxing piano' playlist to find the actual artist they are looking for.

Side effect is that some of it is actually pleasant and that's probably what you found!
