Unless you're a big fan of Zune Wi-Fi functionality, one of the things that's been somewhat lost in the transition to digital music is the sense of camaraderie that comes from getting together to share songs. After all, it's one thing to give someone a mixtape, but quite another to hand over your iPod touch. It's a problem that design student Andrew Pairman is looking to fix with his Social Jukebox, an Arduino-powered music player that lets people embed personal playlists in wooden tokens. The jukebox has multiple spaces for the RFID-equipped tokens to slot into, and it connects to Spotify to load a random song from one of the playlists. One thing you won't find is a skip function, though — you'll have to actually listen to what your friends want you to hear.
