Shazam has been updated, adding Rdio support and other improvements. Connect Shazam with Rdio to listen to tracks on Rdio, and create a playlist out of the music you discover. Just tap Listen on Rdio to start.
Other, smaller improvements have also been made with this release. Sharing tags with email now includes large cover art for tracks and links to Shazam's website for videos and related media. The display of TV results from News has been fixed. YouTube video playback on iPad has been restored. iPhone 4 users experiencing disappearing navigation on the Explore screen will find that this has been corrected as well.
You can grab the update from the App Store now.
