Just tried turntable.fm, the next jukebox
You should check it out when they get some more machines up and running to handle the demand. I hope some bars or cafes start using it so patrons can determine what is being listened to. It allows multiple users to play dj in a specified “room” so if you make a “room” for your workplace and play it around the building coworkers can dj and choose what plays live. It makes easy something that lots people have probably struggled to do, multi-user playlists or itunes audio management over a network.
