I have a weird feeling that this may have come up before as a suggestion....

Many people have been requesting Album-centric features for the empeg. Couldn't marking some playlists as "Albums". Then a "Shuffle Albums" option could be added in the Shuffle menu.

By doing this, you'd get random albums to appear one after another, but the tracks within those albums would play in order.

I'm sure other options and features could be built upon this too.
