I love module music files for their amazing small size to sound quality ratio.
I do propose a solution, not just a request:
I want you to upgrade the sound package of SFML to use audiere since it supports all the current (major) sound types and far, far, far more and it is known to be cross platform and mature, and is opensource/free I think if the license works out for you it would be a great start.
There are other libraries you can use but they have horrendous licensing. I'm using SFML 2.0.Net and I found the supported music/sound types lacking, I can't find any good audio libraries out there. But audiere is great, but no C-sharp bindings exist, plus you'd want to edit the C++ version before you make bindings of it, and so this is again great for that case.
