Spotify refreshed its Windows Phone app earlier this year, but one important feature was missing: free ad-supported streaming. A new update today includes the missing feature, allowing Windows Phone users to stream playlists and music in shuffle mode. The update brings the app largely up to the same functionality as the Android and iOS versions, and Spotify is also improving the search experience and other "additional improvements throughout the app." While the streaming is ad-supported, Spotify users can still choose to subscribe to Premium to avoid ads and sync playlists offline. The latest update to Spotify for Windows Phone will be available in the Windows Phone Store shortly.
