Thank you both for your responses.
Chris CA asked, "Any reason you are burning only one song onto a CD?" I had been having difficulty burning (about which, please see my two posts at
http://discussions.apple.com/thread.jspa?threadID=670534&tstart=0), and in the process of finding a work-around to the problem, I tested the process with a single song. When I finally had a solution, I also had a CD with a single song on it (as it happens, "The Weight" by The Band)!
Now it is working fine, and I know to wait until I have a playlist before burning.
Thanks again.
