Can a CD player play a CD-RW?

A CD-RW is a CD disc that can be re-recorded. Whether or not you can play it on your CD player is determined by two things. If you use software to create an audio CD on a CD-RW then it will play on most normal CD players. If you have a CD player that will play MP3 discs as well as audio CD's, you can copy the tracks from your computer onto your CD-RW disc as MP3 files and again it will play. This type of disc will not play in a normal audio CD player without MP3 capability. Because MP3 files take up so much less space on a CD than normal audio tracks, an MP3 disc has the advantage of being able to hold massively more tracks than a normal audio CD.
