Yet another person who plays the bogeyman card of "conspiracy theory" when what is described is garden variety corruption, only takes a trivial amount of secret coordination in a group smaller than your average terrorist cell, and could probably even be defended as legal with a small legal team (Spotify probably has a big one).

There are a billion ways you could cash in on this. A dead easy one is "music written for hire by a company you own".

Even if Spotify is not doing the slightest thing like this, suggesting that they might is not a conspiracy theory. Quit trying to tar every proposed view of the world you disagree with with that label. You're just making it easier for the actual grand conspiracy theorists.
