rap vs rock

I was just noticing how in middle school the biggest cliques in school was due to music.But lately i have noticed that the two cliques have merged into one school.I think this is due to people broadening their horizons when it come to music.A couple years ago i was listening to hard core rap like biggie,2pac,and The Game.But then i started listening to soft rock such as Jack Johnson and Coldplay.I have since learned that both types of music are good in their own ways.So what types of music do you listen to and why?please comment.
