Limewire is the most popular peer-to-peer (P2P) file sharing program on the Internet. It’s written in the Java programming language and runs on a wide variety of platforms including Windows, Mac, and Linux. Any type of file can be shared, such as music, movies, photos, etc.

Free music usually brings questions of legal issues to mind. That’s because several years ago, the RIAA launched a legal challenge to music sharing sites and the people that downloaded music without paying for it. The claim was copyright infringement, and record producers pushed the cases as far as legally possible in order to stop the practice.
