CD closing after burning

I seem to be having a problem with a CD closing after burning a song and then not being able to add to the CD as it shows no free space. Any solutions? Thanks!

Don’t burn track at once, but disc at once. What program you use to burn?

Thank you for the reply. I’m using Windows Media Player. It sounds as though you’re saying put everything on the CD at once as there is no way to go back and add to it. Sorry if I sound dumb, I am. Never really did this before. Thanks again.

If you have used a CD-R and finalized the disk, it cannot be written to anymore.
