Make cool music. Take a banal, lyrically flaccid piece of music or poetry and rework it. Add something to the lyrics that was only hinted at before. Dig deeper into the song than the original writer was willing to go and say what the original writer was unwilling or unable to say. Avoid the twin traps of parody and snark. This exercise is meant to enhance a piece of work. In this case, to make it cool.
