In a new step in the partnership between Rdio and Shazam, users will now see their tagged Shazam songs in an Rdio playlist, on both Android and iOS. The playlist, called “My Shazam Tracks,” takes a lot of the pain out of having to do things manually. Naturally, the feature requires an Rdio subscription, which is $9.99/month. It’s doubtful that users will sign up exclusively for the feature, but this kind of cross-pollination is only natural between music-based products of this type.
