The words that come out of my mouth creates a song that makes the crippled hearts dance to the beat.

^^ in this line, a possible suggestion:

"Create" instead of "creates"

Because you are referring to what the "words" (plural) do. The words create.

Other than that, I like how you have defined/compared your words to. It doesn't matter how they are but they have a rhythm, a song that people can feel.
