Many DJs boast about the number of songs they have. While variety is great, the fact is that they will only be able to play about 60 to 70 songs in a four-hour show. Having the right 60 songs is a lot more important than having 20,000 songs your crowd doesn t want to hear. After you tell the DJ what type of party you are having and who the audience will be, ask them what type of music they d suggest. You should feel comfortable with most of his or her selections.
Many DJs also boast about having great equipment.
However, your DJ should at least have professional grade equipment. If they list brand names you are familiar with at the local electronics retailer, that is cause for further questioning. Home stereo equipment is not designed to stand up through 4-5 hours of high volume use. For example, typical professional DJ power amplifiers usually have 200 to 400 watts per channel, where consumer amplifiers usually that considered powerful may have only 100 watts per channel. Some DJ companies have more than one DJ working for them.
