When Apple announced at its final Macworld Expo that it was revamping iTunes to enable variable pricing and offer every track in DRM-free AAC format, it also created a bit of a problem for long-time (or big-spending) iTunes customers. Apple would let customers upgrade their existing DRM-protected iTunes tracks to DRM-free iTunes Plus format for $0.30…but it would only enable customers to upgrade their music libraries in one fell swoop. So, if a user has 100 DRM-protected tracks, the only way to upgrade to DRM-free iTunes Plus versions would be to spend $30.00 all at once—and for many users, that kind of up-front charge is more than they want to spend at iTunes in one go.
