Working!?ish
I created a linksheet using some album art. It is a transparent background with the image positioned down and to the left.
I named it the same as the folder the music was in eg. A Foot In Coldwater, and dropped it into my theme folder.
then plugged this into album_playback.xml right after <include filename="./inc_loading.xml" />
<image image="@@artist" w="1280" h="720" bg="1" />
and then tried to play something from that folder. **I'm using media server as the input, and the media library is turned off**
So, to get there, these are the options presented to me along the way:
Audio
Music/Photo/Video -->pick Music
By Genre/By Folder/All Music/Smart Playlist/By Album/By Artist/ etc.... -->pick By Folder
I'm then presented with my folder structure, and I drill down to it from there, finally opening the
A Foot In Coldwater folder which presents me with 4 albums from them.
I scrolled to an album without selecting it, and hit play.
Below is the result. ** edit - I leave the screen in this position all the time and don't use the "now playing" screen ever because you lose the ability to FF songs **

Here's a link until the embed shows up -->

It seems to work. Be nice... it's proof of concept at this point, but now that I see it working, I'll redesign the page more to my liking once I figure out what would look best.
The image lower left is the linksheet, and the image right is the album cover of the current song.
There was one album in this folder titled "Foot In Coldwater" instead of "A Foot In Coldwater", and the linksheet didn't come up, so I can conclude it is drawing off of the @@artist tag.
The end result is that I should be able to select "By Genre", and the linksheet and album art should change during playback.
I'll need a thumbgen template for this, as there is no way I'm doing a few thousand artist by hand.
Below is the full text of my current album_playback.xml if you want to mess with it...
