After a month of lagging behind its Android counterpart, Google has finally updated Google Play Music to include features missing from the initial release. In addition to a UI refresh for iOS 7, the app now includes "I'm Feeling Lucky" radio, which builds an instant playlist based on the user's listening habits, and genre radio stations for paying All Access subscribers. Added creature comforts include the ability to search for genres and auto-playlists — all the better to enjoy the service's more than 20 million songs.
