Never tried it before, but a bit of googling found:
"To create a CD-R from a whole bunch of MP3-files, you can use the 
following command sequence:

for I in *.mp3
do
     mpg123 --cdr - "$I" | cdrecord -audio -pad -nofix -
done
cdrecord -fix

Depending on the speed of your machine, you may want to slow down 
writing to "speed=1" (cdrecord option). If you use "speed=4", your 
machine must be able to play the MP3-file at quadruple speed. mpg123 
consumes much CPU-time! If you are in doubt, try an empty run with 
-dummy (keeps the laser switched off). "
