yes you have to because you need an account to store the music on.
To use an iTunes Gift Card to pay for your songs click on the Redeem link in the Quick Links box (top right) on the iTunes store home page.
no you need to set up an account before you can use a gift card
there is no such thing of a you tunes gift card. it is called an itunes (notice how there is no space in itunes) gift card. an itunes gift card is for buying music off of the itunes store for your ipod.
No you do not.
You must be viewing the iTunes app on the iPod Touch. The 'redeem' feature is used when you want to add iTunes cards to your iTunes account. This allows you to do it while you are on your iPod, so you do not have to be connected to iTunes.
If you mean purchasing songs from iTunes on an iPod, Yes. On an iPod touch you may download music from either a credit/debit card or an iTunes gift card.
Once an iTunes gift card is added to an iTunes account, the balance cannot be removed. Plus, you cannot get a refund for the card, because you already scratched off the PIN number to add it to your iTunes account.
yes
Yes,you can go onto your account settings for iTunes and then click Edit payment information. You can enter an iTunes card as long as you have the code on the back that's only when you start creating an account when you already have an account you go to itunes and go to redeem and type in your itunes gift card code
When you redeem your gift card, you will have to open an account. However, you do not need a credit card to do this, just the gift card will do.
Go on iTunes, then go on the iTunes store and click "Redeem", type in 16 digit code on the back of your iTunes gift card. After that it should add the money on to your account and then just spend the money. Hope that helps.
