I don't know how you have stuff set up right now, but let's say it's:

Root
-Tempo
--Slow
--Fast
-Genre
--Rock
--Country

and then inside each of those playlists is a mishmash of tracks. (Or do you just have one big root playlist?)

Create a new playlist called, say, Album-Artist. Inside that, create a playlist for each artist, and inside those, playlists for each of their albums. So, for example:

-Album-Artist
--Pixies
---Bossanova
---Trompe Le Monde
---Surfer Rosa
--Wilco
---Summerteeth
---Yankee Hotel Foxtrot
--Beatles
---White Album
---Rubber Soul

Mark "Artist-Album" as "ignore as child". This means that if it's a child of a playlist you've selected, like the root playlist, it won't descend into it. That way, you'll keep the order of your meticulously crafted playlist(s) straight. And as long as you do this all within emplode without uploading new tracks, you won't waste any significant space by having multiple copies of the same track on the empeg.

Then, when you want to listen to a whole album, navigate to it and hit play. If you're listening to your mix, you can go to the album, hold down the down button on the play playlist icon and select "Insert" or whatever the most appropriate queuing option is.

Actually, jEmplode should be able to create those playlists for you via it's soup function, but I haven't played with it enough to be able to tell you how to do it for sure.
