those files are mp3's and not the type a normal cd player uses, the esiaest way for me to tell you how o convert the files is to tell you to download Nero burning rom the free edition, and than after you've installed it, when you open it a window will pop up answer the questions with your own judgement untill you get to where it asks you which type of cd you'd like to burn select audio than continue answering the questions like before. which ever number I'm at... go to where your songs are located, than move the songs from the right window into the left one. and click burn!!! and it'll play on a normal cd player
