Looking to usurp rival competitors like Spotify and MOG, Sony today launched its Music Unlimited streaming service as an iOS app. We told you in January that it was coming, but today the free app officially hits the App Store with subscriptions starting at $3.99 a month for varying access to the service’s 15 million+ songs and playback features. There is also a 30-day free trial of the premium service.

Previously only available to Android users and Sony products such as PlayStation 3 and Blu-ray players, the service offers two paid subscriptions options, including: a $4 Basic plan that provides basic channels and access to your own library; and a $10 Premium account giving you access to on demand playback for Sony’s catalogue, offline listening. The more expensive packages also offers the ability to create playlists, and access charts, new releases, and premium channels. Unlike Spotify, which recently debuted its iPad app, the Music Unlimited app does not have an iPad-specific version.

The Sony Music Unlimited app is available in the New Zealand App Store now, and it should hit the United States and other supported markets soon. As of March, Sony offered the service in 14 countries including the U.S., Canada, Australia, France, Germany, Ireland, Italy, New Zealand, Spain, United Kingdom, Denmark, Finland, Norway, and Sweden. A full list of features for Basic and Premium subscribers is below:
