Part of the Terms of Service...not quite sure what this entails. Very strange to me that this is not being covered as news yet...

8.6 Without limiting the above, by submitting your information through the Service Applications, and/or by utilizing Social Network login details to login to the Rdio Service, by linking your Rdio Service account with any Social Network account, or by otherwise providing Registration Information to Rdio, you grant Rdio a non-exclusive license to use, reproduce, transmit, and display the information obtained from these third parties and any Registration Information in connection with Rdio’s operation of the Service Applications and/or performance of the Rdio Service (subject to the other terms and conditions of these Terms of Service, including Section 4.1).

8.7 You will: (a) promptly update your Registration Information to keep it true, accurate, current, and complete; (b) maintain the confidentiality of your login credentials; (c) properly exit from your account at the end of each session. You will not: (a) select or use the Social Network account or email address of another person with the intent to impersonate that person; (b) use a name subject to the rights of any other person without authorization; (c) allow any other party to use your account and/or password. You agree to notify Rdio immediately of any known or suspected unauthorized use(s) of your account or any known or suspected breach of security, including loss, theft, or unauthorized disclosure of your user name or password or Social Network account login details. You understand and agree that you will be liable for all activities that occur under any account created for your use, even if you did not commit such activities. Rdio is not responsible for any loss or damage as a result of someone else using your account or password, with or without your knowledge.
