How to authorize iTunes after email changes

I’m having problems with Apple’s “authorization” process that gives my PC the right to play songs in the iTunes program. This started when I changed email addresses and switched my iTunes account to the new address. I then authorized my PC to play iTunes music. But when I try to play music, I get a message saying it’s not authorized. The iTunes program won’t even play non-Apple music I copied earlier from CDs. The account info is the problem. When you authorize a computer to play music in iTunes, you log in with a password called your Apple ID. This Apple ID is linked to your iTunes account, and every time information in the account changes — as it did when you changed your email address — the Apple ID and the song-authorization process can be affected. In your case, changing the account meant that songs that were previously authorized to play on your PC no longer are. There are two ways to fix this:

If you use an Apple ID that’s not your email address, try switching your iTunes account back to your old email address, then make sure your PC is authorized to play your iTunes music. You should then be able to play music.

If you use your new email address as your Apple ID, try highlighting a song in the iTunes library that you purchased from the iTunes store. Then go to the top of the screen, click “edit” and choose “song info.” In the re- sulting menu, click the “file” tab and look at the heading “purchased by.” The name in parenthesis is the Apple ID used to buy the song. You should then authorize your computer with iTunes using that Apple ID.
