This option is the best to choose for a backup for two reasons. Data CD or DVD: In a data CD or DVD, *all* songs in a playlist, regardless of file type, are burned.
This is advantageous for burning CDs for use in MP3-capable portable CD players or MP3-capable car stereo CD players, because these devices do not presently support AAC.
If there are any AAC or Protected AAC files in the specified playlist, they will not be included on the CD.
In previous iPod 101 segments, we learned to create both Manual and Smart playlists. However, none of us can fully escape the need for “old-fashioned” CDs every once and awhile-we use them to listen through other devices, share with friends, and backup our music collections. ITunes is great for playing your tunes on the computer, and the iPod is the undisputed champion of playing personal on-the-go music.
