One of the many many valid reasons to drop Zune and it's marketplace is the DRM validation error you see below. The vast majority of the music I had purchased last year is completely gone. There's no refund, the music doesn't exist on the service anymore, the files are just garbage now.
Here's the unbelievable error:
"This item is no longer available at Zune Marketplace. Because of this, you can no longer play it or sync it with your Zune. There might be another iteration of it available in Zune Marketplace."
Did anyone else have Microsoft's licensing policy as a reason to jump ship? Or was the word "Microsoft" enough?"
