EMusic.com Inc. has had enough of Napster users raiding hard drives and downloading songs that EMusic's customers had to pay for. The company announced Tuesday morning that it's flipping the switch on a way to track an MP3's "acoustic fingerprint." The company's new software will continually search for any EMusic tracks being distributed through the Napster application, then send out an instant message giving the person 24 hours to stop distributing the track. If the user doesn't comply, the company then asks Napster to block the person's account. Full story. -- Ben Charny, ZDNet News
