Using iPod

Using iTunes, you can preview, purchase, and download your favorite songs from the 

iTunes Music Store (available in some countries only). There are hundreds of thousands 

of songs available for purchase. You can use an Apple Account to purchase songs from 

the music store, or if you have an America Online (AOL) account, you can use that.

Open iTunes and click Music Store in the Source list.

Click the Account button and follow the onscreen instructions to set up an account or 

enter your existing Apple Account or AOL account information.

You can only have music from five different Music Store accounts on one iPod.

For more information about the iTunes Music Store, open iTunes and choose Help > 

iTunes and Music Store Help.

• AAC (M4A, M4B, M4P) (up to 320 Kbps)

• Apple Lossless (a high-quality compressed format, available using iTunes 4.5 or later)

• MP3 (up to 320 Kbps)

• MP3 Variable Bit Rate (VBR)

• WAV

• AA (audible.com spoken word, formats 2, 3, and 4)

• AIFF

A song encoded using Apple Lossless format has full CD-quality sound, but takes up 

only about half the amount of space as a song encoded using AIFF or WAV format. The 

same song encoded in AAC or MP3 format takes up even less space. When you import 

music from a CD using iTunes, it is converted to AAC format by default.
