Digital Trends – Walmart has issued a memo to all music licensing partners and informed them that the digital music store at âmp3.walmart.comâ will be shutting down on August 28, 2011. All music content will no longer be available for download and users are urged to download DRM-free tracks before becoming unavailable. After the store closes up, tracks containing DRM will still be supported and will continue to work as the DRM servers are being kept online. DRM-enabled tracks will be available in WMV format and contain the same device restrictions as when purchased.
