Audio CDR???
What's that? I have never bothered even looking for one and have
never had any problems whatsoever with the CDRs I have music on.
Why should I? The laser doesn't know the 1s and 0s represent
music.

But the stand-alone burner knows whether there's a code on the blank
media saying "I'm a certified Audio CD!". Some would argue it
protects you from cheap-and-nasty media. Some would consider it a
scam.
