The joy that Apple decided to sell DRM free music on their popular iTunes plattform was overshadowed by two elements. The first one was that the DRM free songs would cost $0.30 more which could not really be explained. The second element was discovered after users were actually able to purchase drm free songs at iTunes.
Account information, namely name of buyer and account name, remained as information in the DRM free files. While this should not be a problem for everyone some users would have at least preferred to receive information about this before making the purchases.
