Yahoo announced that effective Sept 30, they will be shutting down the servers needed for customers who need to reauthorize their legally purchased music. Yahoo previously had announced the demise of their Unlimited Music Store.
DRM encoded tracks have caused a commotion since they were introduced as a piracy-fighting tactic. Users purchasing new computers and operating software upgrades have had to reauthorize their playlists each time. Not surprisingly, that came with a high degree of customer frustration.
As DRM finds its way out the door, more online music retailers are abandoning the technology. In a recent move, Microsoft announced they would shut down their servers in 2011. (After initially pegging an August date). Yahoo suggests that users burn their DRM tracks to CD while they still can. Thanks Yahoo.
