The music industry is hoping that in exchange for DRM free music and the attendant freedom (and reduction of guilt associated with DRM stripping), the consumer will be okay with paying a higher price for music. Apple inked a deal with the three largest music distributors: Sony, BMI and Warner, to provide DRM free music. The cost of the songs, though, will be in excess of the $.99 standard.
Update: Apple announces that as of end of Q1 2009, all music at iTunes will be DRM free. You’ll have to pay $.30 for each song you previously purchased to get a DRM free copy. Or you can download software and strip the DRM yourself.
