Rappers vs. Record Labels

In recent months, i've taken notice on how influential rap/hip-hop has become around the world. The front page of my local newspaper had a picture of a rapper in Isreal, and another one from Jerusalem. I thought those pics to be pretty poignant in the fact that the rap/hip-hip culture has direct roots in black american culture that has literally reached to every metro area around the world. But over the years rap has been tarnished by the artists who don't bring any value to the genre. Artists who spit out garbage basically. These artists have become what the conservative set has targeted as being the definition of rap/hip hop culture which to them means guns, violent black men, drugs and degredation of women.

So this issue has made me wonder, why are rappers being villified and held accountable for their behaviors and language, but not the record label executives who hire and keep these villified rappers under contract to represent their record label? Shouldn't the record labels also be responsible for the words that come out of their artists mouths? Should they be held accountable for the violence that sometimes stem from this kind of music?

What are your thoughts?
