How can I Burn audio CD's in ITunes?

[John Moore]

Hey all. I put a blank CD in my superdrive, and told it to openn  
ITunes. I had imported some things from another CD and I wanted to  
burn them to this one. HOwever, when I selected the Music playlist,  
went to the File menu, and selected "Burn Playlist to Disk", it was  
dimmed. Is there something I should be doing?
