The pure fact that they are sung isn't enough to promote the words to the title of poetry, as the definition of poetry comes from the use of the use of vocabulary and grammar, not from the context in which that vocabulary and grammar is read.

AC/DCs lyrics, however (although Moley disagrees), are a form of poetry but they are very simple and clear poetry. They do use metaphor, rhyming and specific meters, so they definitely count as poetry.
