Lupe Fiasco has never been one to hold his tongue when it comes to waxing eloquent about certain social and political issues. Now, the Chicago emcee takes aim at violent music in a new diatribe.

Yesterday, Lupe published a series of Tweets decrying violent lyrics in hip-hop. According to Lu, violent music provides "positive reinforcement for negative actions," and that many artists hide behind the excuse of art reflecting life to justify it.

Later on in the line of discourse, Lupe owned up to his own use of violent lyrics early in his career, saying that he's become fed up with hip-hop playing the soundtrack to news stories like the 13-month-old Georgia baby who was recently killed in a shooting. Ultimately, he said that some emcees at least need to own up to the violent content of their songs.
