If your computer's got a good soundcard, you can look on the back and find a little stereo jack connector marked "Audio In."

That being the case, gluing shut the CD player accomplishes nothing, except the waste of a good CD player.

How about taking a ball peen hammer to the CD player and bust open the case? A little crude, but certainly effective.

Or better yet, take a ball peen hammer to the heads of the Industry Execs responsible for this bone headed move.
