I have heard many stories of “iPod Dj’s” ruining a reception by playing inappropriate music. It takes experience and an unselfish DJ to play songs that a crowd wants to hear and dance to. It is nearly impossible to plan a good wedding dance ahead of time, especially without a lot of experience performing for an audience. Also, in most situations, it is not easy to set up and run high-level audio equipment correctly, and If they are not using professional-grade equipment, there is a good chance it will over-heat or malfunction at a high level of output. An iPod is not a DJ. It is a music player that has no clue who the guests are and the type of music they want to dance to.
