Digital entrepreneur Michael Robertson’s MP3.com and MP3tunes music services were disruptive in their time, but in 2013 he’s focusing on a related industry: radio. Having previously launched time-shifting service DAR.fm, now he’s unveiled something new called Uberstations. It’s a website gathering streams of 14k FM/AM radio stations, sorted by US zip-code, tracking what songs they’re playing in order to recommend other stations playing similar tracks. “We think this is a real advance in online radio experience,” Robertson tells the LA Times. “We play all the stations in one beautiful Web experience, and we’re tracking real-time what’s playing on thousands of stations.” There’s some obvious competition in the form of TuneIn, which has 40m active listeners, similar recommendation ambitions, and global reach with its site and apps. Uberstations’ challenge will be to differentiate itself from that rival.
