Meaning "without digital rights management". DRM-free music tracks can be
purchased and
downloaded online and are currently offered by the iTunes Store and Napster,
as well as other online digital music vendors. DRM-free music may be purchased
cheaper than those sold under
DRM, and may also be of lesser quality. Most
stores offering DRM-free music will provide users with options to upgrade the
the higher quality DRM version by charging a small fee.
