"Toasting (rap in other parts of the Anglo Caribbean) or deejaying is the act of talking, usually in a monotone melody, over a rhythm or beat by a deejay. It can either be improvised or pre-written. Toasting developed in Jamaica, before taking up that name and being part of the sound system era. A similar sound is found in mento and now can be heard over musical styles including ska, reggae, dancehall, dub, grime, hip-hop, soca and bouyon music. The combination of singing and toasting is known as singjaying. " - Wikipedia
