YouMixer is a new type of music site. Here, you can start a mix and invite all your friends to contribute to it. The music mixes you find on this site were created by actual groups of friends, for actual parties. They range from the most current songs, to interesting compilations of classics.
Use YouMixer for your parties. It is like iTunes, but free. And not only free, but it features music videos. Oh, and people can add new songs to the mix at any time -- even at the party -- just by coming up and searching YouTube.
Go ahead, try it. You can start a mix by selecting an existing YouTube playlist, or by cloning one of the popular mixes on the site, to use as a starting point.
