iTunes will begin selling DRM free music in May. All of the music will be coming from EMI and will cost $1.29. The cooler thing is that you can upgrade your music if it is available in the DRM free version for $0.30 per track. The music will also be encoded in 256-bit AAC.
This is pretty great and I think this is a big step towards showing other record companies that selling DRM free music will be able to bring sales back up.
