In fact, that looks like the one I was talking about...

and no.  I don't/can't use mythmusic (too many tracks, it's unusable), 
so there's no real reason for me to look into it for mythweb.  I'm also 
lazy and want to wait for the backend to start handling streaming, 
rather than dealing with nfs/smb mounts and all of that sort of thing.
