Shazam doesnt want you to leave its app, and has partnered with music streaming service Rdio to make that happen. A new update to Shazams iOS app that went out today — and is headed to the Android version — lets you play full versions of songs youve identified using the companys tagging technology. It requires being a Rdio subscriber, and allowing Shazam access to your account. Once youve linked the two, you can also add songs to Rdio playlists right from Shazam, listen to full tracks from Shazams explore and pulse sections, and see songs youve played in Shazam in your Rdio history.
