Never tried mpg321 in collaboration with cdrecord to create an audio cd, 
so I gave it a test with the following sequence of commands (which, of 
course, I had found out after some trial and error)

mpg321 -w test.wav -v Chaka\ Kahn-\ Aint\ nobody.mp3
cdrecord dev=/dev/hdd -pad -dao test.wav

This gave me a proper one track audio cd ...

mpg321-0.2.10-6.rhfc3.ccrma
cdrecord-2.01.1-5
on fc3
