Mobile DJs are the most common. They generally work parties and special events (ie: weddings, birthdays, etc.) onsite. This sort of work usually entails entertaining a wide array of tastes and age groups, as well as a bit of MC'ing.
Radio DJs are the least common. Their task is to make sure there is never any dead air time by filling it with either their words, or music. Again, there is a certain mass appeal that needs to be worked on and being a Mr. Personality is important.
Club
DJs can be found, but aren't nearly as prominent
at mobile DJs. They have a very specific clientele (age group wise) and
are expected to play the latest and greatest all the time. This sort of
DJing often requires the most technical know-how on mixing since style
and uniqueness are critical to establish a name for yourself and the club
you work for. Rave DJs tend to fit into this category because of the similar
mixing skills required.
