While there absolutely are (great) artists in the dance music world recording their own acoustic instrumental riffs or vocals, I'd feel comfortable betting that a majority of the tracks we know and love that feature recorded parts like that are sampling someone else. Its part of the art form, and certainly anyone who has ever DJ'd is familiar with the idea of making something new and great from someone else's initial creation. Dance music is samples all the way down - sometimes even samples of other tracks that sampled some other genre.
