auditory cues work sometimes, but its difficult to figure out how loud you need it to be so that you can hear it but it doent wake you up.

Also you mind has the interedting ability to instantly adapt the dream so that any influence from the physical world seems like part of the dream. You could give it a shot though =) You will also have to get used to playing that song and doing a reality check when those certain lyrics come up. Becaue if its not a part of your routine, it probably wont make its way into your dreams.
