A live mix is influenced by how the audience responds to it. You may be wearing them out too quickly, or you may want to drastically switch things up a little. Having "suggestions" on what the next track could be, allows you to choose between keeping the mix rolling, going to a high-profile track or take the crowd down deep. After linking quite a few tracks you will have a network of links that allow you to change the mood of the mix depending on the response from the audience, using tracks that all mix really well into one another.
Thanks I didn't find the right solution from the Internet.
