Microsoft was nice to make a file available that contains all of the preloaded content that comes with the 4, 8 or 80GB devices. They haven't made available the preloaded stuff from the 30GB or the special edition Zunes.

So if you want this material all over again, or you're like me (with a 30GB) and you want the stuff that the other Zuners get click here.

Update: Julio was able to locate the original preloaded content for the Halo Zune 30.
