Background Music

I would like to create a playlist of possible background music for my game. What this will do is choose a song at random and play it softly in the background. When the song ends it will choose another and play it, ect...

Problems I have with sound: When I make an audio source in the game and set its "Rolloff Factor" to 0 so that it can be heard from anywhere, whenever I move my camera, the sound glitches and sounds very distorted until I stop moving the camera. Does anyone know what is causing this and how I can fix it?

Just turn off 3D audio for the music files; you don't have to mess around with the doppler or rolloff factors.
