Yes of course. If you choose to pay through Paypal, you can fund your Paypal account (e.g. through your credit card) in Dollars, Pounds or any other currency, that Paypal supports. At the moment you will be billed automatically in Euro, the exchange rates will be automatically calculated through Paypal.
If you require an invoice showing Dollar, please contact us.
In short: If there is Paypal available in your country (currently over 100 countries worldwide), you can license music at Proud Music!
