Thanks for the post. This is where a huge lawsuit would be a good thing!
Remember in 2004 when TurboTax pulled some similar stunt? They hue and cry was pretty load and they came back on bended knee apolgizing.
Sony is notoriously bad with respect to DRM. They assume EVERYONE is a pirate and restrict their stuff accordingly. I say - Sony keep your cruddy music!
Which is why I no longer buy Sony products.
