Music played by a DJ is different from music played by a band. First of all, you can hear your favourite hits in the’ originals (even if it is a recording). Also,  a good DJ will smoothly mix the music material, taking into consideration the overall atmosphere mood of the guests, and will contribute a “live” element to the known and unknown compositions. The DJ can be more flexible than a band,  as far as the music variety is concerned, since no live music is involved. Normally, a DJ’s services are in demand, when the audience consists primarily of younger people.
