Once you have the Rdio app on your phone, launch it, enter your email and tap Sign Up to get started. Rdio will email you a confirmation link. If needed, you can edit your email address or resend the confirmation email by tapping the Edit Address or Resend button.
Alternatively, you can sign up using your Facebook account by pressing the Facebook Connect button. You'll be prompted to allow Rdio access to certain areas of your Facebook account which will be used to create your Rdio account.
You'll receive a confirmation email from email@example.com asking you to verify your email address. Tap the link to confirm.
Complete the action using the Rdio app. Happy listening! If you need help figuring out what to do from here, check out out the Android App Guide.
