Given that Doug doesn't know precisely what power a song provides until after the song provokes a reaction, that would imply that he dies at the same time he figures out what the song does. Of course, you could claim that the first time he used the power, Doug was overcome by a feeling of lassitude that lead to him lying down and watching as his physical body got further and further away, only for him to be resuscitated by someone else after the song came to an end. He'd probably then freak out before password locking the song.
