Just recently I was in a situation where I was discussing with a friend that it would be cool to have the Jukebox option at a party. Well, here is one solution to it! Anthm is a nice little app that lets you start a song queue where friends can throw in their records chosen from Rdio's library of millions of songs. Perfect would be if the app at least also inter-operates with the Android OS.
Check the video to see how it works.
