So... You take an existing classical piece or phrase from a song (always in a 4/4 time signature), loop it endlessly with amplified bass, then brag or complain about your money/lack of money, sex life/love life, general anger or violence, etc. and become a huge icon while some greedy record label steals all your money.
Okay, so maybe I'm describing rap at its worst. Plenty of more underground rappers may talk about political issues, more complex personal struggles, social classes, psychological states of mind, spirituality, religion, and the like, but it's still not music. It's poetry, and the musical element is all but removed. Rap is something I may look up and listen to hard for a good couple of minutes, but if I want to indulge in something melodic, I opt for a different genre.
