The glamorization of criminality in the favelas is also frequently viewed as another negative consequence of funk carioca. Some funk songs, belonging to a style known as "proibidão" ("the forbidden"), have very violent lyrics and are sometimes composed by drug-dealing gangs. Its themes include praising the murders of rival gang members and cops, intimidating opposers, claiming power over the favelas, robbery, drug use and the illicit life of drug dealers in general. Authorities view some of these lyrics as "recruiting" people to organized crime and inciting violence, and playing some of these songs are thus considered a crime.
