I'm having a bothersome issue with the music on the original Lemmings in DOSBox. When I play the second level in a session, the game will correctly play the second music track the first time. However, if I fail the level (whether by ESCing/nuking, or running out of time, or failing to meet the percentage requirements) when I replay it, the music goes back to the "Canon in D" variant (track #1) until I pass the level. Then it will resume with the third music track, again on the first play-through, going back to the Canon whenever I fail the level.

I'm sure someone here knows exactly what I'm talking about, as I've seen it happen on L1 Let's Play videos on YouTube, so it's not just me. My question is, is there some sort of setting in DOSBox I can twiddle that will fix it, or is it just a DOSBox bug that I can't do anything about? (If it's a DOSBox bug, is there someone that knows enough about the way music selection was done in L1 that could help explain what's wrong in DOSBox so that we could submit a comprehensible bug report?)

I'm playing through Mayhem for the first time so I'm sure if this is unfixable I will be hearing a lot of Canon in D!  Thanks in advance for the help!
