> at least in USA the courts have repeatedly rejected the notion of "moral rights" Well, the problem is that the US is the farthest from the international norms of copyright, so while in the US you can do that, in other countries (maybe except Canada if I remember correctly) there's a concept of absolute moral rights. So assuming that Spotify can fought it back in court in the US, other countries like Japan might give it to Adelle, and so the shuffle button might only appear in the US while other countries might think if they want to adjust moral rights.
