Spotify’s free mobile version is now available for Windows Phone 8 and 8.1 users, who can download the app from the Windows Phone Store, Spotify said Tuesday. Windows Phone users can participate in the standard 30-day free trial offered by Spotify, but only Sprint customers are eligible for the free three-month or six-month trials depending on their mobile plan, a Spotify spokeswoman told us. Previously, only the premium $9.99/month version of Spotify was available to Windows Phone users, the spokeswoman said. Premium subscribers get on-demand play, higher quality audio, uninterrupted music with no commercials and the ability to download music and listen offline, according to Spotify. With the free version, users can listen to and shuffle playlists, it said.
