Fair use? "Honestly, for your first film, you don't have enough money to fight the music industry."

Film documentarians often pick up bits of songs (or glimpses of TV shows) and are shocked at the prices asked for the right to use the material -- perhaps far more than the cost of making the film. And now that everyone's cell phone rings a copyrighted song, they might have to pay $10,000 just to keep the footage where the phone rings.
