Yes, the music should be audible; this is not a subliminal music program.  If you can’t hear the music, a) make sure it’s playing by listening to it without the Dreampad, b) check your volume level, and c) make sure your connections are good.  We recommend listening at a relatively low volume level.  If there is ambient noise in the room, such as a fan or humidifier, this will interfere with your ability to hear the Dreampad music so we suggest either turning off the ambient sound or raising the volume of the Dreampad.
