how do i get rid of 39 cents on my account to later switch the country to canada?

hello everyone, i have a US account with 39 cents on it that i obviously cant spend of anything. I live in canada now and i have 20 free song downloads that id like to use but am not allowed to on my US account. I cannot change my country with the balance that i currently have on my account (39 cents). anyone know how i could reset the balance and change my account country?
