Documentation correction: Promoted songs

[eyand]

In the documentation for the Mobileclient.get_promoted_songs() method, the docs say that the method determining the songs returned is unknown. When I run this method my liked/thumbs up auto-playlist is returned. Not sure if that is the case for anyone else.

Haha, that was actually what it was named for a long time. Past Simon was pretty convinced that wasn't the case (#282), though I can't actually seem to find more context on it.

In my case it seems to be only thumbs up from Google library, uploaded are missing
