For a while now I've been asking friends and other people to name a famous, living painter. Then I would ask them to name an average, living rapper. You can guess the results. People don't know any painters, but have no problem with naming moderately successful rappers.
I realize part of the problem is the nature of both activities - songs are going to be played on the radio, tv, even as soundtrack in movies. Even if you tried to avoid a mainstream song you couldn't. Also rappers are viewed as celebrities and rock stars.
How could an artist achieve that level of fame? How could paintings achieve the level of exposure that songs have?
