Roxio burner and CD-RW Question. PLEASE HELP!!!!!

[bballkid]

I have a CD-RW that i once used to copy music into my Xbox's harddrive.
Now i have gotten some new songs i want to put into my Xbox, but I want to use the same CD-Rw.I once read that you have to "keep the cd open" in order to put new songs into it. What does that mean and how could I do it? Here are some info that might help.

*The Cd-RW is a "Maxell" brand
*I am using my Windows Media Player to burn cd's.(Which i beleive uses Roxio)
Thnx for your help.

i think you're confused about multi-session recording.

if you already copied the songs off the CDRW disc onto the hard drive of the Xbox, you can safely erase the CDRW, burn the new songs onto it and copy them to the Xbox.

no need to write everything in bold.
