Audio CDs. There are two main types of CDs that you can create with CD burning software: audio CDs and data CDs. To ensure that you create a CD that will play anywhere it is important to choose the option to burn an Audio CD or Music CD and not a Data CD. A data CD containing for example MP3 or WAV files will play happily on your computer but is unlikely to play in a standalone CD player or in-car CD player (note that some modern CD players will play data CDs). An audio CD will play on any standalone or in-car CD player and in your computer and in modern DVD players. Audio CDs do not have files or a file system like data CDs and other computer storage media, but consist essentially of a stream of bits on the disc in a single spiral track with a TOC (Table of Contents) index.
