Chobit, there's a post two before MT's post with the links to the music with links to the Ogg Vorbis website, and also to a ogg converter program that also works fine, if you want to just convert them back to .wav or .mp3 format.
My pieces were actually recorded as .wav files, but I converted them to .ogg as that is what the client is coded to load.
Really though, if you are having trouble getting the music converted, or enabling your media player to play them, let me know. I will convert the files and e-mail them to ya.
After all, I don't want you to miss out. Especially Fallon_dark's piece. It is truly lovely.
