iTunes 10 for Mac: Create your own MP3 CDs
You can use iTunes to create CDs of music in MP3 format; the songs sound as good on the CD as they do in iTunes. (MP3 is a high-quality, Internet-standard encoding method.) You can listen to MP3 CDs you create on MP3-capable CD players or on your computer.
Before you burn a CD, you must create a playlist containing the songs you want on the CD. You can store more than 12 hours of music, or about 150 songs, on a 650 MB CD-R disc. (You can see the size of the selected playlist at the bottom of the iTunes window.) If you plan to play the CD only on your computer, you can use a CD-RW disc.
You can burn songs in MP3 format only. If your playlist includes songs in formats other than MP3, such as songs purchased from the iTunes Store, you need to convert them to MP3 format before you can burn them on a CD.
To create an MP3 CD:
Create a playlist containing the songs you want to burn to the disc, and make sure all the songs you want to include have a checkmark beside them.
Insert a blank disc.
Choose File > “Burn Playlist to Disc.”
If “Burn Playlist to Disc” doesn’t appear in the menu, it means that the playlist you selected can’t be burned to a CD because it contains items with usage restrictions.
Select MP3 CD as the Disc Format and click Burn.
If the playlist contains more songs than fit on a CD, iTunes burns only the number of songs that fit on one disc, and then asks you to insert another disc to continue burning the remaining songs.
If the playlist contains iTunes Store purchases that are not iTunes Plus songs, you can burn the playlist to a CD up to seven times.
Songs you download from the Internet may be of different quality because other encoding formats were used.
