Once you have the Rdio app on your phone, launch it and tap "Try Rdio for Free" to get started. Enter your email address and 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.
You'll receive a confirmation email from email@example.com asking you to verify your email address. To do this, check your email (and your spam folder, just in case), and tap the link to confirm.
Complete the action using the Rdio app. Enter your account details and tap Save. A Terms of Service pop-up will appear, and if you Accept, you’ll be logged into the Android app’s Rdio dashboard. Happy listening!
