 With the combination of OpenMG with MagicGate, Sony intends to restrict the files to be only moved instead of copied, artificially emulating the restrictions of physical objects.However, as of the most recent releases of Sonicstage, files can be "checked out" of the library an unlimited number of times to a portable device, without the need to "check in" any of them.There has been anecdotal evidence that OpenMG modules tend to "choke" reading corrupted MP3 ID3 tags.
