With Apple's recent agreement with the three remaining major record labels that were holdouts on stripping DRM from iTunes downloads, all music purchased from the iTunes Store is now available in higher-quality 256-kbps AAC encoding without DRM. To upgrade the songs I already purchased, I am getting hit up for 30ยข apiece. My grand total? A little over $180. But of course, I feel compelled to upgrade. It looks like some of the stuff I most want in the better format--like the rarities included in The Complete U2 digital boxed set--may not be available, though, which is a bummer. Ah, the price of progress!
