It is asking for a back up payment method (credit card or debit card) when you use your PayPal balance. If you are paying for a subscription service, they more than likely require it.
just subscribed to Spotify Premium and it seems that I actually authorized Spotify to take the monthly charge automatically - and this comes to me a bit strange... I´d have a hypothetical question - what if I die? 🤔 The payment will go on without anybody to stop it?
