Synced music is stored locally on your iPad, and does not need a WiFi or cellular data connection to play. You can sync as much music as will fit in your device’s storage, and it will be playable as long as you have an active trial or Unlimited subscription.
Managing Synced music
To sync music, find an album or song, longpress it or tap the gray ⊕ icon, and select "Sync to Mobile." Music synced for Offline play is marked with an orange mobile icon. You can also use Rdio’s web site to mark music for offline syncing, which will happen the next time you launch Rdio on your iPad.
Remove albums and songs from your synced collection by tapping the orange synced icon and selecting "Remove from Mobile".
Add tracks to your existing Playlists by tapping a song title and selecting “Add to Playlist.” Choose which Playlist you would like to add to from the menu.
To delete a song from a Playlist, open your Playlists from the left-hand navigation bar, longpress the song, and select "Remove from this Playlist".
The search bar is located at the top of the app menu. Type what you’re looking for—the dropdown will update as you type. If you’re not seeing what you’re looking for there, tap the Search button on your keyboard to see your results sorted by Artists, Albums, Songs, Playlists and People.
You can share songs, albums or Playlists while you’re on the go—just longpress the item and select Share. Post it to Facebook, Twitter, or copy the direct link to share elsewhere.
History shows a record of what you’ve been listening to on Rdio.
Stay up-to-date on new music via the New Releases section. View new releases from this week, last week, or two weeks ago.
In the same bar you can access the playbar and timer, back and forward track, and the Airplay control.
When Rdio is active on another device, you’ll see “Rdio is playing elsewhere” in the now playing bar at the bottom of the app. In this mode, you’ll be able to play/pause the music, change what’s playing, and toggle shuffle and repeat controls remotely.
To play Rdio from your iPad instead, tap the player control bar, then tap "Play here instead".
