This is what also confuses me, and if that is the case, wouldn't borrowing a book off a friend, or even a magazine be illegal? First to answer cyco's quote, no that is not stealing. That is copyright infringement. It is still illegal, it is not prosecuted as harshly though. That's why the MPAA an RIAA are propagandizing that copy movies/music is stealing, so they can get more out of it or something. Now for Led's, your analogy doesn't work. If you borrow a book from a friend, the friend no longer has access to it. If you borrow a CD, your friend doesn't have access to it. If you borrow a CD and then copy the songs to your computer, then give the CD back without deleting the songs from your computer, you have committed copyright infringement, which is illegal. A few people so far have explained it pretty well. Copying music is NOT stealing. It is still illegal and (from my subjective viewpoint) morally wrong. Oh yeah lol, forgot about that, works the same way as roms and iso's.
