Zune is a multi-tasking program for media playback and communication with Zune portable players and Windows Phone 7 phones. This program can successfully play music stored in MP3 and WMA formats, videos in system-supported formats and serve as a photo viewer. The application offers the possibility of editing metadata found on the music disc and cataloguing it and grouping it into playlists.

You can manually or automatically sync the collected music to your portable device (Zune player or Windows Phone 7). The program automatically converts the found music and videos to the optimal format for the target device. Known as Dorado code, the program also enables you to buy apps for Windows Phone 7 and Zune HD as well as music and movies in the Zune Marketplace.

Music can also be played as part of a Zune Pass subscription. Zune also allows you to automatically synchronize podcasts (also in video form) and is an essential tool for updating Windows Phone 7 phones.
