If you've lost or deleted songs or other media in your collection, it's easy to get them back.
Restore music from Zune Marketplace
Music you downloaded or bought from Zune Marketplace is easy to restore.
Restore lost or deleted music from Zune Marketplace
We are currently unable to replace MP3 songs that you delete or lose. For this reason we highly recommend that you back up your MP3s by burning them onto a CD. WMA files may also be burned onto a CD, but you may only burn the exact same playlist a maximum of seven times.
Restore podcasts from Zune Marketplace
Podcasts are not included in the list of Zune Marketplace downloads, so if you lost podcast episodes, you may have to restore them separately.
If you have an active subscription to a podcast series, the most recent podcasts from that series may be redownloaded automatically.
However, if you kept any past episodes as favorites, you will need to manually redownload those lost episodes to restore them to your collection. For more on podcast subscriptions and downloads, see Subscribe to Podcasts.
Restore items from your computer
If you accidentally deleted media files from your collection but did not delete them from your computer, you can restore them to your collection with just a few clicks.
