I've heard all the arguments, but I still come to same conclusion using Napster to get copywrited material is plain old theft. Using Napster, Internet users can access an almost endless supply of MP3 music files that other users have saved on their computers for this purpose. No longer do you have to spend your hard earned cash on CDs. You can just go to the Napster site, download the free Napster software and download all the free music you want. The problem is the music isn't theirs to give away.
Music is copywrited, and is the intellectual property of the artists who created it.
Downloading that music is robbing those artists of the money they would receive when you buy their album. It's still stealing. In many cases that's fine. A variety of musicians post samples of their music on their own, or their label's website. If a band wants to put samples out there, that is their choice.
