But did you get permission in writing, you might forget you gave yourself permission and take legal action.
IMHO stupid laws should be broken, thats how they get changed. Even the BBC has how to articles on backing up music, and plenty of journalists have openly admit to the heinous crimes of recording stuff from the radio, ripping Cd's to use on mp3 players, and the travesty of listening to the radio in the office without buying a special license.
I do love the way that people think that piracy is something new, in th70s/80s/90s everybody recorded stuff off the radio, tape decks (often made by sony) featured a button to copy from one tape to another, and some had high speed synchro to do it quicker. Now we get Sony, etc complaining about people copying stuff when its always been them that sell and make the kit to do it.
