Burning CDs or MP3 in iTunes!
By default, iTunes burns CDs as Audio CDs that can play in any CD player. Many cars now come with an MP3 CD Player and it is possible to burn CDs that contain a lot more songs. It is however not necessary to use an application like Toast to do so. It is possible to modify iTunes' preferences so that it burns MP3 data CDs. You can change it in the "Burning" tab of the Advanced preferences.
