The documentation for shuffle/shufflable in the iTunes Applescript dictionary is really confusing, at least for me. As I read it shuffle seems to be a property of a playlist (not a state of the program itself) but in the regular UI there is no such property for playlists (I would love to have it so I could set some playlists to always shuffle by album while other should always shuffle by song).
Anyway, I want an Applescript that enables shuffle by song/album and plays the currently selected playlist. How do I write the shuffle part of such a script?
