// In this demo, we use Mix_Music *Mix_LoadMUS(const char *file)
// Where file is the name of the music file to use. 
//
// SDL_mixer supports music and sound samples from the following formats:
// - WAVE/RIFF (.wav)
// - AIFF (.aiff)
// - VOC (.voc)
// - MOD (.mod .xm .s3m .669 .it .med and more) using included mikmod
// - MIDI (.mid) using timidity or native midi hardware
// - OggVorbis (.ogg) requiring ogg/vorbis libraries on system
// - MP3 (.mp3) requiring SMPEG library on system
// - also any command-line player, which is not mixed by SDL_mixer...
//   that requires a command to play with.
