What are you trying to stuff up roxio's nose baby? Are you sure you're not trying to burn playlists rather than the actual audio files? There are updates for windows roxio if you checked. Unless you're already updated. Just drag & drop the actual songs onto roxio & it should do the deed! Make sure you choose audio cd unless you really want to burn an mp3 disk. See
Burning an audio CD from your MP3's And try burning at minimum speed instead of max speed!!!
Oh are you sure they are mp3 & not that crappy wma other format.
