Ahhh!
Now I know why your handle is familiar. I lurked at AVSForums-HTPC for quite a while [actually I've posted there as about MJ a waaays back when I finished the search and found what is by far the best].
I haven't looked at the API MJ publishes - but it's not hard to imagine building the album 'play list' dymanically based on the meta-info MJ stores - like what the album name is
I'm psyched there's a link between AVS-HTPC and MJ. I was thrilled when I learend that Monkey's Audio [Matt] was linked with MJ.
I took a quick look at CDLobby and it looks a good bit like Rhino-Banga's Album-View module for MJ...
My media is stored with the filesystem reflecting some of the meta-data (c:\music\artist\album). If you use a similar scheme you may be able to queue the album by paying the folder using the MJ Media Server/SMB/NFS.
best regards
BTW I too am using a PC as a dedicated media server - audio only at this point. I use TightVNC to interact with MJ when I want to select albums, make play lists etc. These days I generally leave my collection running on random ( minus a block list ) and use the pause and next track commands. I was using Girder with IRMan but when I dropped the video support so I could move the jukebox elsewhere (garage) it no longer made sense for me.
