You can't delete individual songs, but you can erase the whole disc. Just make up the new list of songs you want to burn, put the CD-RW disc in the drive, then press the Windows Media Player 'Copy' button. The Roxio Basic CD Burning Applet will appear and tell you something like "The playlist is too large to fit on the CD". Hit the 'Burn' button on the applet anyway, and another window will pop up with the message "This CDRW is currently unusable for this burn. Would you like to erase this disk and then burn?" Click 'Yes' and you are good to go.
