the whole CD. Use cdplay stop when had enough.

-w my_file.wav my_file.mp3
Create a wave audio file from an mp3 audio file. Useful if you wanted
to write a regular audio CD from mp3s--you have to convert the mp3s to
the *.wav format first. Don't be surprised the conversion is slow--decompressing
mp3s is very processor intensive.

lame
input_file output_file
MP3 encoder. You may need to download and install it yourself (standard
Linux distributions avoid supplying it because of disagreement about patents
on the mp3 compression technique).

Really cool, while it lasts. Gnutella and FreeNet will soon replace them->it
