hmmm without the blues there owuld be no rock n roll. without rock there would be no soul. without soul there would be no rap. rap is ok, but musically it is repetitive. I guess it can be poetic but musically speaking it is generally ( yes there are a few exceptions) simple changes and repetitive beats. Yes rock has simple changes, but it is not nearly as repetitive. We have been using the same chord changes since the mozart and beethoven era.
