What to Do with Music You’ve Bought

As you know, the iTunes Music store gives you a lot more freedom to use your downloaded songs than other music services. There are a few restrictions, though.

Play It on Five Computers

You can play Music Store–bought songs only on an authorized computer. Authorization is Apple’s copy protection scheme.

Between work, home, and the family network, not everyone spends time on just one computer these days. So Apple lets you play your Music Store songs on up to five computers at once: Macs, PCs, or any combination. You just need to type in your Apple user name and password on each computer. Each must make an Internet connection to relay the information back to Music Store headquarters.

Authorizing Computers

You authorized your first machine when you signed up for an Apple Account for the iTunes store.

To authorize a song to play on another computer, follow these steps:

1. Find the song you want to transfer.

   This step, of course, involves finding the song on your hard drive.

   Method 1: Open your Home → Music → iTunes → iTunes Music folder. Music Store files are easily recognizable by their .m4p file name extensions.

   Method 2: Just drag the song you want out of the iTunes window and onto your desktop.

2. Copy the song to the second computer.

   Copy the song file onto a CD or USB flash drive; email it to yourself; transfer it across the network; or whatever method you prefer for schlepping files from machine to machine.

   Deposit the songs in the Home → Music → iTunes
