More popular funk carioca artists usually compose two different sets of similar lyrics for their songs: one gentler, more "appropriate" version, and another with a harsher, cruder set of lyrics (not unlike the concept of "clean" and "explicit" versions of songs). The first version is the one broadcast by local radio stations; the second is played in dance halls, parties, and in public by sound cars. Recurrent lyric topics in funk carioca are explicit sexual positions, the funk party, the police force, and the life of slum dwellers in the favelas. Another large part of the lyrics is the use of the world around them – mainly the poverty that has enveloped the area. This is usually denounced in the lyrics and the hope for a better life is carried through many of their messages.
