Heya! First of all, thanks for your interest in using my album in your game! Actually, the album is free, the $10 price is just a suggestion in case anyone wants to support me or contribute in some way. And yeah, unfortunately, this is a limitation with Stripe because I live in Brazil and receive payments in another currency :/ itch.io doesn't really give me many options besides PayPal.
But from what I can see here, I think you managed to complete the payment, right? I hope everything went well, and if you run into any other issues, just let me know!
