I've looked at music careers, and picked a few that work. My joke about going to jail first was a slam on most artists in these genres. If you become a rapper/Hip-Hop artist, you wouldn't go to college because it is a poor investment of time and money. These genres are fading and only a small handful rise to the occasion of being a fully-fledged rap/hip-hop artist.
My advice to you is invest in a colledge and a good job before you go off to seek your dream. No one will offer you a good job if your resume says your High School education and that you were a music artist.
