Status: Stood by it. Working as intended™

What actually happened

PlaysForSure was Microsoft's compatibility mark for music stores and devices: buy DRMed Windows Media files from Napster, Urge or MSN Music, and per the logo on the box, they would play for sure. Then in November 2006 it came out that Microsoft's own new player, the Zune, would not play any of it, because the Zune worked only with Microsoft's new Zune Marketplace. Partners had built stores and players around the certification, and customers had bought music on the strength of the sticker. Microsoft kept selling PlaysForSure files at MSN Music even while advertising the Zune alongside them. The program was discontinued by 2008, and every purchase made behind the logo became a countdown.

This one is officially acknowledged.
