If I sync Rdio to my ipod, will it only sync locally hosted music or ALL music files?
With an active Unlimited subscription, you can Sync songs to your mobile device using one of Rdio’s mobile apps. Synced music is stored directly on your device, and does not need a wifi or data connection to play. You can Sync as much music as will fit on your mobile device, and it will remain on the device as long as you have an active Unlimited subscription. Synced music is marked by an orange phone icon.
No local music files on your device can be stored or played within the app.
