1. Learn about all genres of music. Often you may know of a couple hit songs in a few genres but that is not enough. Try going to sites that try to help independent labels. Often these sites have songs that are free and therefore you are able to sample before downloading. Also make sure you learn about all the hit songs in most genres because those will be the ones that the crowd recognizes and most likely they will like it if it's a hit. 2. Legally Download all of the music you think four out of five people like and can be danced to. By doing this it encourages even those who don't particularly like the song to go with the flow and dance to it.
3. Play a song you think a group of friends might like. If eighty percent or more say they liked it then you correctly associated the song to the group.
4. Develop your charisma. Try to be a someone that attracts attention in a good way when necessary. Also know when to step back and let the group dynamic take over. Constantly vying for attention will make people uncomfortable.
5. Learn party games designed for a memorable experience while eliminating a large number of people last.
6. Ask a friend who has a party that you were invited to if you can do a free gig there. This will allow you to observe the crowd's reaction to you.
7. If DJing is right for you then begin to get a few small gigs at a price much lower than an experienced DJ would charge. A few ideas are a senior center dance in which you will be exposed to different music tastes than yours, a dance at a local youth center such as the Boys and Girls Club, and maybe a company gathering.
8. After the smaller gigs if you still want to do it then partner with a few people and start your own business or work for an existing one.
