  Hi folks,
 I'm batch-ripping and encoding a lot of my CD collection to
 put on my mp3 player.  I've noticed that a number of CDs contain
 an apparently spurious first track that's apparently very short
 (about a tenth of a second) and contains no audible signal.
 What the heck is the point of this track?
 e.g.
 $ sndfile-info track00.cdda.wav

is that the extra, hidden file that the record labels put on some cd's,
in an effort to stop digital extraction of the disc? i can't remember
too much about it, and i don't think they use this method much anymore.
