We could not publish this information before testing it ourselves, from different iTunes Stores. Yesterday, Tuaw showed that DRM-free music tracks and album available from the iTunes Plus are tagged. When opening the file in a text editor, one can find the name of the original purchaser. We do not consider this as a major problem as one is not supposed to share music on P2P networks (this is part of the license agreement)
