The sound itself is a mix of repetitive chants and drum machine rhythms. Many of the drum machines (and the rhythms they produce) were previously more well known in specialty genres of dance music. The delivery of the lyrics, as with other Southern rap, is based on a rhythmic "bounce" which is very effective in clubs. In fact, several crunk songs have been banned in venues due to how wild the crowds can get.
Popular crunk-style acts include Bonecrusher, Lil Jon & the East Side Boys and Three 6 Mafia.
