Often these tracks are used for "toasters" rapping heavily rhymed and alliterative lyrics. These are called "DJ Versions". In forms of sound system based reggae, the performer using a microphone is referred to as the "DJ" or "deejay" (where in other genres, this performer might be termed the "MC", meaning "Master of Ceremonies", or alternately, the later developed slang terms: "Microphone Commander" or "Mic Control"), and the person choosing the music and operating the turntables is called the "selector" (sometimes referred to as the DJ in other genres).
