Piracy is known as illegal copying of copyrighted information. Piracy is a buzz word in recent days in music and entertainment industry. Most of us download music from internet without paying any royalties. It is estimated that most of the downloads are illegal without giving a proper source for figure. Illegal downloading of music files reduced the music sales. Musicians should be compensated for their art, but pirating the music in an illegal way is wrong. However, there is simply no way to prove that every illegal download is a lost sale, and that those same people, if they were not illegally downloading music, would not be content with just listening to the radio, streaming music online, or borrowing music from a friend.
