Webopedia's Did You Know... When Is Downloading Music on the Internet Illegal?"
For many people it is as simple as opening one of many peer-to-peer file share programs, selecting the tracks, downloading and burning to a CD-ROM. What isn't so simple about downloading music is the copyright protection laws that people break everyday by downloading some music tracks off the Internet. To make matters even more muddled, some music can be lawfully downloaded, and for those that aren't, laws regarding the sharing and downloading of music on the Internet vary from country to country.
