http://news.teamxbox.com/xbox/15069/New-Zunes-Available-Tomorrow-Zune-Originals-Revealed/For the first time, consumers also will have the option to customize their Zune player with laser-engraved designs and personal text through a new Web store called Zune Originals. Customers will be able to purchase a Zune player directly from Microsoft at http://www.zuneoriginals.net and choose from a collection of laser-engraved artwork designed exclusively for Zune by 18 internationally recognized artists.
Please follow the steps below to build your library using the metadata in the file rather than the 1.0 data store:
Close Zune.exe
Open (for Vista) C:\user\{your_username}\AppData\Local\Microsoft\Zune or c:\documents and settings\\local settings\application data\Microsoft\Zune the equivelent on XP
Find the CurrentDatabase_365.wmdb (that is the 1.0 data store) rename it to CurrentDatabase_365Old.wmdb
Find the ZuneStore.sdf (that is the 2.0 data store) rename it to ZuneStoreOld.sdf
Restart Zune.exe, it will find all the media files in your monitored folders and add them to your collection based on the metadata in the files.
Just a quick tip for those of you using XP: The location of your SDF and WMDB files will be:
"c:\documents and settings\\local settings\application data\Microsoft\Zune".
Note that some of these folders are hidden by default, so depending on how you navigate there, you may have to turn on viewing hidden folders in explorer from Tools->Folder Options->View->Show hidden files and folders.
On Vista, it's:
"c:\users\\appdata\local\Microsoft\Zune".
