Piracy is the illegal copying of copyrighted material.  This can be, but is not limited to music, games, and videos.

Music piracy can be defined as the stealing of music.  One scenario could be borrowing a friend's CD and burning a copy for yourself.  Also, downloading music from the Internet if the song's royalties are not paid.

  A positive consequence of stealing music is that you get free music for your own personal enjoyment.  You can also profit from piracy.  However, more often than not, piracy will result in the negative consequences.  Caught pirates are sued and occasionally served with jail terms.
