Surely some enterprising plaintiff-side attorney can generate a lawsuit from the reasonable expectations of consumers to continue to have access to the music they paid for:
Customers who have purchased music from Microsoft’s now-defunct MSN Music store are now facing a decision they never anticipated making: commit to which computers (and OS) they want to authorize forever, or give up access to the music they paid for. Why? Because Microsoft has decided that it’s done supporting the service and will be turning off the MSN Music license servers by the end of this summer.
MSN Entertainment and Video Services general manager Rob Bennett sent out an e-mail this afternoon to customers, advising them to make any and all authorizations or deauthorizations before August 31. “As of August 31, 2008, we will no longer be able to support the retrieval of license keys for the songs you purchased from MSN Music or the authorization of additional computers,” reads the e-mail seen by Ars. “You will need to obtain a license key for each of your songs downloaded from MSN Music on any new computer, and you must do so before August 31, 2008. If you attempt to transfer your songs to additional computers after August 31, 2008, those songs will not successfully play.” …
Bennett insists that MSN Music keys are, in fact, not yet expiring. Technically speaking, that’s true—if I authorize one of my PCs, never get rid of it for the rest of my life, and never upgrade its OS, I will be able to play my tracks forever. But as some of our readers note, this technicality is not rooted in reality—the authorizations will now expire when the computer does, for whatever reason.
