As xismn pointed out, you could use OS specific function calls to do so. You could use system calls to load a program and song (like linux, I did system( "vlc break.mp3");[/code] (not really recommended). You could use the sound functions from libraries like Allegro, SFML, or SDL or look for a specific sound API. Other than that, would be stuck writing your own if you didn't want to use an existing one.
