You do get into an odd legal area, though, when that license allows you to burn the music to a CD. Once the music is on a CD, can the license extend to say that you can't then rip the tracks, which is otherwise covered under fair-use? (Remember the controversial "Rip, Mix, Burn" slogan that Apple itself used to sell iMac's?)

I know that the legal system doesn't operate under mathematic principals, but if I can legally transform from A to B and from B to C, why should it be illegal to directly transform from A to C?
