Typing "music piracy" in Wikipedia will redirect you the "Copyright infringement." No sweat, it's the same thing. Wikipedia defines "music piracy" or "copyright infringement" as follows:
Copyright infringement (or copyright violation) is the unauthorized use of material that is covered by copyright law, in a manner that violates one of the copyright owner's exclusive rights, such as the right to reproduce or perform the copyrighted work, or to make derivative works. (Wikipedia)Definitions in other sites do not vary as much. But in my arguments today, I''ll show that such definition is not only outdated and impractical, it also lacks in scope.
