Windows Phone version of Spotify is updated
Spotify for Windows Phone is free from the Windows Phone Store. But the premium version of the app allows you to play any song at any time on any device. The premium version of Spotify also allows you to listen to your music without an internet connection. And of course, paying $10 monthly for the service means no ads!
If you decide to go with the premium version of Spotify, you can cancel anytime. With Apple looking to undercut Spotify and drastically slash the price for streaming music, we could see a drop in price for the premium version sometime this year.
