As of now, PaySafe Prepaid is the only payment option for Spotify's one-time payment plans. Since the prepaid card is almost virtually unknown and you have to find a local vendor and pay in amounts of $10/$25, this makes the one-time payment plans virtually useless. As a result, Spotify essentially requires users to sign up for a recurring payment plan if they want to use something they already have on hand, such as a credit card or PayPal. There is little to no reason why we shouldn't be able to use a credit card/PayPal for a one-time purchase plan like every other online site. Thanks for reading, promote it if you support the idea!
