How can I pay with credit card when I have gift balance
I would like to pay for some iTunes songs/apps with a credit card. However, I have a gift card balance.
How can I specify the credit card as a payment method?
You can't specify how items are charged, if you have a balance on your account then that will automatically be used up first.
Buy you could try gifting the songs and apps to yourself - you can only gift via a credit card (you can't use a balance for it), and I think that you should be able to gift to yourself (I haven't tried it)
