In hip hop and electronic music, "producer" is pretty much synonymous with "artist". In hip hop the MC is the one whose voice you hear, and the producer is, well, everything else: the beats and melodies in addition to the more traditional producer stuff like arrangement and mastering. Electronic music also follows this paradigm. As there is typically no live voice (any voice is typically coming from samples), the producer is the entirety of the production.
