Unfortunently I have to agree with earlabs. Other than what we have posted to get you folks to burn your music to CD from REAPER, there are better ways i am sure.
I use REAPER to burn music I mix to CD just to have it played in other systems for review prior to a pre-master. To really do this right, you need third party software that is specific to the task.
Anyway follow this link, I provide a step by step procedure to burn from REAPER for multiple songs...
