Hi,
Check whether the songs you’re trying to burn have extra dots or special characters in their filenames, especially between the file name and the extension. That can sometimes cause compatibility issues and prevent the songs from being burned to the CD.
If you're still having trouble after that, click on Organize in WMP then select Options. Go to Privacy tab and uncheck all the options under Enhanced Playback and Device Experience. Click on Apply and OK then check if it resolves the issue.
