n If some of the songs are skipped when you play an MP3 disc, your music player may not be compatible with all of the music formats on your disc. For instance, some systems can play MP3 files, but not WAV files. For more information, consult the documentation that came with your device.

n Many more audio devices will play an MP3 CD than an MP3 DVD or BD.

n You can create an MP3 disc containing copy-protected WMA files, but those files will only play on the computer used to create them.

n Once an MP3 disc is recorded on a write-once disc, no additional data can be added. An MP3 disc recorded on a rewritable disc must be erased before data can be added.
