What are you trying to play the CD in? Is it your computer or a CD player? If you directly burn MP3 files to a CD you'll end up with a data disc, rather than an audio disc. You'll be able to put that disc into a computer and play the files but the majority of CD players won't recognise it as a valid disc. CD players expect to receive a CD that actually has a SINGLE file on it...
