Janus Friis with Niklas Zennström, who disrupted music distribution with the Kazaa file sharing service and phone companies with Skype, unveiled their Twitter-like version of a digital music service at the crack of midnight Thursday morning.

Rdio offers instant access to more than 5 million tracks from all the major labels and several indies to listeners in the United States and Canada through a web browser, downloadable software or mobile app. It’s available for free for three days and then for fees of $5 (web only) or $10 (web plus mobile).
