although the artist may have messages that may not be positive on their projects, i believe the relavence is that those same artist are showing a positive side and also are the role models for these kids and too be honest if they fav artist can show both sides its going to show that alot of these negative messages arent always true but more a marketing tool and not real life. plus its goin to open alot of doors to opportunity and may help "rap" with its general preception as a negative influence.
