For some Djing is an art and skill of finding music that moves the crowd. Once in a while it may be ok to post playlists but if you have spent hours and hours of time digging for songs, I wouldn’t want some other DJs to come by to swipe up my hard earned music research. There are a few other reasons why I wouldn’t post my playlist as well. However, if you are spinning songs that are so basic and easy to find, especially if they will die out in a few months, use it temporarily as a marketing tool. Temporarily is the key word because in the end you want people to come out to listen to you whether it is your online radio show or at a venue.
