Along with new and updated Twitter, Facebook, and Skype apps, Microsoft announced that popular music streaming service Pandora would be available on Windows Phone 8. While the app will not be available at launch, Microsoft says it is expected to release in early 2013. When it finally hits the now 120,000 app-strong Windows Phone Store, however, Microsoft will be offering Windows Phone 8 users a complimentary one-year subscription of ad-free music.
