The names of DJs and similar artists are very varied, varying from a generic name to stage names, from joke names to descriptive names, as well as from a whole spectrum of these names. This name generator mostly focuses on nickname-esque names, some descriptive, some more joked, and some of which are different together. The "DJ" prefix is arbitrarily applied to names, so names have two versions technically, but some names appear to be better with or without the DJ prefix. So maybe you want to play more with this feature.
