What are the disadvantages of DRM?
DRM imposes severe restrictions to the end user that may not immediately obvious, so you should carefully decide whether you purchase music that is DRM protected. For instance, DRM is often applied in a way so that it ties your DRM protected music to only one certain computer, so you may not be able to copy and listen to your DRM protected music on a different computer. The music files may be further restricted so that they cannot be synced to a mobile device, played only a number of times, or played for a limited time only.
