Walmart began selling DRM-free tracks in its music store in August of last year. 13 months later, the mega-corp has decided to follow the footsteps of so many others and hit the kill switch on its DRM management servers. As noted in an e-mail to customers, Wally World will be making the final transition into a fully DRM-free MP3 store on October 9th, and in order to keep those DRM-laden files playable on anything, it's recommended that you burn protected files on a CD on the double. If you choose to ignore this message, you'll be unable to "transfer your songs to other computers or access your songs after changing or reinstalling your operating system or in the event of a system crash." Heed the warning, kids.
