I own an original music disc (applies to more than one actually), but, as I currently only have a netbook without a CD-drive I have downloaded the same disc through a torrent, one encoded in FLAC and one in MP3 (probably isn't relevant for the subject, but just to be noted). The MP3 version is for my portable player. It was just simpler to do it that way than to find a computer with a CD drive and rip the disc...
What I want to ask is are these downloaded files legal. The torrent protocol itself isn't illegal, so that isn't a problem. I also own the physical disc so as far as I know, I have the legal rights to have a backup copy.
But as I didn't do the ripping and encoding myself, and it is not actually a digital copy of the very disc that I own, but someone else's disc; can these files be viewed as a backup copy? Maybe someone with legal expertise or something could clarify...
