Just a production note:

Someone remarked above about the music being different from one video to another. That is not a minor point if you ever sell your videos or allow others to do so. One of the problems with video is that it picks up the sound too. Even for audition tapes (which are commercial use too) if you don't own the rights to use the music, you may be asked to pay those who do. Stripping off the sound or getting the OK from the right folks can save you some money and embarrassment. Another trick is to add a sound track of drums only and then strip off the rest of the music. People requesting audition tapes aren't taking the risks you are. Be careful!
