A glitch in the newest iTunes software update has caused many people to lose previously purchased music and movies. Though they've fixed the problem and apologized for it, many people are unsatisfied.

"Most of the music I have purchased online from Apple's iTunes Store has been deactivated," wrote Martin of Suisan, Calif. "I have purchased approximately $140 dollars worth of songs and videos from iTunes Store, which currently is worthless due to the fact that iTunes will no longer play any of them."

When you deal with a company that is dead set on controlling everything you do with your legally purchased media, you're best off not using their product. Even if you decide to use iTunes, make sure to strip the DRM off using the Hymn Utility so you can copy or use the music freely.
