To make what you are trying to say clearer let me say this... You cannot play mp3's in mp3 format off of a CD meaning that you cannot burn a CD as a Data CD containing a bunch of mp3 files unless you have a CD player that will support it... You can however burn MP3's to CDR as an Audio CD as long as the burning program converts the mp3 to wav on the fly when it is burning... The con is that you can only hold 72 or 80 minutes of music on the CD as opposed to the 650-700 MB of mp3 files that you would be able to if your CD player supported it. Basically, I understand what you are saying, but this is what you meant to say.
