Last week, Rdio addressed one of my longstanding criticisms of the service by launching high-quality AAC streams with a 320 kbps option for Unlimited users:

Today we’re happy to announce we’ve converted our entire catalog of over 30 million songs to high-quality AAC audio. Listeners around the world now have four sound quality settings to choose from across iOS, Android, and the web. All Rdio users can choose between data-efficient 64 kbps all the way up to 192 kbps. Rdio Unlimited subscribers now also have the option of listening in pristine-quality 320 kbps. Plus individually select your audio settings for a variety of uses, whether you’re using Wi-Fi or cellular streaming or listening to offline downloads.

Rdio is late to the 320 kbps party, but better late than never. I like how the updated iOS app has individual settings for streaming and download quality over WiFi and Cellular connections.

And speaking of the iOS app, it was also updated with new iOS 8 features and support for CarPlay. I couldn’t test the latter as I don’t have a CarPlay receiver, and the fact that Rdio is now optimized for the iPhone 6 and iPhone 6 Plus is pretty much a given with app updates at this point.

The use of interactive notifications by Rdio is clever: if someone shares a song or album with you, you can swipe down on the Rdio notification to view it or start playing it. The Play button has to launch the Rdio app first, but it’s still a nice shortcut that should remove some friction from sharing with other Rdio users.
