Ministry of Sound, the well-known nightclub/record label in London that puts together various compilations of dance music is suing Spotify, claiming copyright infringement in a case that will fascinate copyright fanatics. This one goes a few layers deep, so stick with it: MoS is not suing because the music on Spotify is unauthorized. Nor is it suing because of anything that Spotify itself did. Rather, it’s suing because some users of Spotify have put together and published “playlists” (a feature found on pretty much any music playing software ever) that mimic some of the compilations that MoS has released. Again, the music itself is all legally authorized and licensed to be on Spotify. The complaint from MoS is merely that some Spotify users have put them together in the same order.
Probably a bad sign if your business is so reliant on the order in which music is ordered that you feel compelled to sue to protect such nonsense.
