I've seen several poems posted and a song is a poem with music basically so I'm sure it counts. : ). I think it works wonderfully well as a prompt-filler. It's a parody of the film song and uses elements from the dwarves' journey so it crosses over perfectly. Unless this uses a farthing you don't want to spend, I think it's worth posting. You decide. I enjoyed it very much so do as you see fit. As for me, I consider the prompt as filled. I'm very happy with it.
