Good move, iTunes!
Great news from apple. They are removing DRM (i.e., crippled music), moving to tiered pricing and allowing songs purchased over the air to be transferred back to a computer. I’ve recommended and wished that Apple would do this for a long time (as I’ve posted here before). I think these moves will be good for consumers and for apple.
For my friends and family, starting in April you should consider purchasing music from iTunes again. And don’t forget that Amazon also sells DRM-free music.
