Rdio teams up with Shazam for instant music discovery, celebrates 20 million songs

Shazam Integration

Rdio is once again using its considerable API flexibility to team up with another company, this time Shazam, in an effort to drive more traffic to the streaming service’s mobile app.

As of today, if you “automagically” discover a song within Shazam you’ll be given the option to “Listen Free on Rdio.” This applies to both the free and Encore versions of Shazam, which boasts music discovery prowess to over 300 million people, adding 2 million more each week. The user will be given the option of directly opening the Rdio app from within Shazam, and if he or she is already a subscriber, listening to the song in its entirety. New users without a subscription can hear a 30-second clip, which is still quite impressive.

This integration is live today in Canada, U.S. Australia, Brazil, U.K., and Mexico, and applies to Shazam and Rdio on both Android and iOS. This is amazing exposure for Rdio, which is growing quickly but competing against stalwart services like Slacker Radio in Canada and, more importantly, Spotify and Pandora in the U.S.

To help entice more users, Rdio is also announcing it has hit 20 million songs in its library, 2 million more than the last time they counted their coins. From my perspective, most albums get simultaneously released in Canada and the U.S. these days, whereas in the past Rdio may not have gone that extra mile to secure the rights to such material.

If you haven’t signed up for a free trial, Rdio provides new users with 7 days of unlimited streaming, on- and offline.

It also has apps for iOS, Android, Windows Phone, BlackBerry and the web.
