Streaming music on Windows Phone just got a great new app today in the form of Spotify. Microsoft held a special event in NYC to promote Windows Phone, where a select few including Tom Warren from WinRumors were on hand. Andy Lees, Microsoft’s Presend of Mobile Communications, announced the availability of Spotify in the Windows Phone Marketplace today. Spotify allows you to stream a vast array of streaming content, but does require a Spotify Premium account to stream to your Windows Phone. Premium accounts are priced at $9.99 per month.
