There's no difference between lyrics and poetry. Words are words. The only difference is the people who are in academic positions and call themselves poets and have an academic stance. They've got something to lose if they say it's all poetry; if there's not music to it, and you have to wear a certain kind of checkered shirt or something like that. It's all the same. Lyrics are lyrics, poetry is poetry, lyrics are poetry, and poetry is lyrics. They are interchangeable to me.
