If you’re a new Rdio use, you can now sign up at rdio.com, and enjoy up to six months of free music, depending on how many songs you stream. Free streaming is available through the Web or Rdio’s desktop apps for Mac and Windows and no credit card is required for the trial.

The meter at the top of your profile page will keep you updated on how much free music you have remaining each month and at any time you can upgrade to Rdio Web, Rdio Unlimited, or Family Plan to stream unlimited music.  Subscriptions start at $4.99/month.
