Some media files, such as images, music, or video clips, are
protected by digital usage rights. The activation keys for
such files may allow or restrict their usage. For example,
with some activation keys you may listen to a music track
only a limited number of times. During one playback
session you may rewind, fast-forward, or pause the track,
but once you stop it, you have used one of the instances
allowed.
