When I have a song stuck in my head it does keep me awake, which is the problem. You see, when you WILD, you have to fall asleep. You have to be sleeping to dream. The trick is to stay aware. Now, there are some people who do respond well to music, and there is a variation on WILD that uses music to maintain focus. I want to say it’s called M-WILD, but I’m not sure
Still, whatever you use make sure you can focus. I’ve fallen asleep with the TV on and the noise was just incorporated into the dream (i.e. DC’s were acting out what I was hearing). Music can be the same, so whatever you use, keep the focus on dreaming.
