deejay

In Jamaican music, a deejay ( DJ ) is a reggae or dancehall musician who sings and "toasts" to an instrumental riddim
Deejays are not to be confused with DJs from other music genres like hip hop, where they select and play music. Dancehall/reggae DJs who select riddims to play are called selectors. Deejays whose style is nearer to singing are sometimes called singjays
