Well, I agree with Johnny_Rock, I prefer the PC version. The sound quality depends on the sound card you have. If you have a Creative one with support of SoundFonts you will have a great song quality.

It is a technology to improve MIDI type playing, by having better sound samples. You can find on Internet much better SoundFonts than Creative drivers hace, as Chorium or FluidR3. On the other hand, the bigger SoundFont you use, the more RAM you will need, as it loads entirely on RAM. For example, FluidR3 is about 150 MB, Chorium is more or less 25 MB.

I personally recommend Chorium. (http://www.un4seen.us/files/ChoriumRevA.rar)

Enjoy the game! :)
