Sonos has converted its Controller application to run on the Android platform. And, like its iPhone equivalent, it's completely free to download.

The Sonos Controller for Android application gives full control over the company's music streaming system, effectively turning a mobile handset into a CR200 (the proprietary touchscreen device that currently retails for £279). It connects with your home network wirelessly and can therefore talk to any Sonos kit you happen to have, be it the ZonePlayers 120 or 90, an S5 boombox, or one of the bundles.

It offers connection to your entire music library stored on a computer, media player or NAS drive, with cover art and metadata support; and can be used to access Spotify, now that it is on the platform, Napster, or plenty of other partners, allowing you to play music on your Sonos kit from cloud-based libraries through an Internet connection.

There's also an incredibly powerful search functionality.

To work, the app requires you to have Android 2.1, and will run on any device with a screen size of HVGA 320 x 480, WVGA 480 x 800 or WVGA 480 x 854.

It will be available from March on Android Market, and Pocket-lint will have a play with the new version at Mobile World Congress next week in Barcelona.
