Spotify is absolutely huge in the UK at the moment and the release of a mobile application is inevitable. It is almost a given that Spotify will release on the iPhone however it appears that Android has beaten the iPhone in developing the Spotify application.

The official Spotify Android app has been demoed for the first time at Google’s I/O event in San Francisco yesterday. You can see Spotify running on Android in the below video, and while it is still a work in progress it does appear to be functioning quite well.

The Spotify Android app will work over 3G, and it will also cache songs you request so you can listen when you’re out of signal too.

It will also work with the Spotify desktop client, letting you drag and drop tracks for preloading.
