Twisten.fm is a mashup of Twitter and previously reviewed music service Grooveshark, that turns Twitter into a giant random-play jukebox. Still in its incubation phase, the mashup provides a current list of the most recent micro-messages involving music and a link to the song in the Grooveshark catalog for your listening enjoyment. If you’re looking for something new and random to listen to, culling tunes from the millions of tweets sent every day is a pretty novel way to go about it. When you’re in the mood to just hit shuffle, how do you open yourself up to new tunes? Share your monotony-breaking music sources in the comments below.
