Rap is the most beautiful form of poetry there is, you don't just have to write 3 sentences and a chorus twice to finish a song. You actually have to have content, subject matter. There are beautiful lyricists that exist in this world outside the realm of what you probably hear on the radio. There are rappers that talk about real issues. Army of the pharaohs in one example, jedi mind trix. You would probably enjoy both of them.
