This is where it gets tricky. I bought it through my eebay account and changed details to wifes for logging in to spotify. But the payment came from my paypal, different email. It was set up a pre authorised payment.Looks like your email was used and that maybe means the setup included using PayPal and all that's needed for that was your email but surely it takes you to PayPal for your password...you change details or you give them the details ?
