Syncing songs to iPod strips and changes various tag information

When syncing songs to my ipod, i noticed today that over half have had the year changed to zero

I don't know why or how the information has changed, on my original pc it's all correct.

So somewhere along the line the ipod plugin strips and changes that tag info, and who knows what other information gets changed

I'm eagerly awaiting the new version of songbird and the new version of the ipod plugin hoping it fixes all the double ups, ipod crashing and other bugs :D
