you could just set the ones you want to shuffle to always shuffle and leave shuffle off

Discussed before.

This doesn't work for playing the whole player, as it would sub-shuffle albums and it would shuffle the order of the albums, but wouldn't shuffle it as a whole group. In other words, you'd get a shuffled Rush album, then a shuffled Bruce Springsteen album, then a shuffled N'Synch album, but not everyone all mixed up.

Unless they changed that behavior without my knowledge.
