I also worked around it by including the track number in my song title / filename, zero-padded. That still left the "can't listen to all of an artist's albums one after the other" problem (which JReceiver also addresses), but I figured if I really wanted to do that, I could've made the titles "<Album> <Tracknum> <Song>".

Instead I built the multicast listener and wired the whole thing up to Obsequeium so I could throw songs onto the end of the queue without disturbing what was playing
