Change Pandora Billing from Apple (iTunes) to ANYTHING other than Apple (iTunes)

I created my Pandora account when I had an iPhone, approximately 8 years ago. I no longer own any Apple devices and am tired of trying to manage my Pandora subscription through Apple (iTunes). On top of that, my billing card expired in April and I had to listen to cruddy Pandora ads until I could work on it tonight. From what I can gather, after about three hours of excruciating help links, multiple reset passwords and crazy amounts of multifactor authentication, that I need to cancel my subscription through Apple (iTunes). My concern though is that when I head down the path of cancelling my Pandora subscription via iTunes, I can see that I will still be able to access my Pandora account through 6/27/21; HOWEVER, am I'm going to lose all of my channels and preferences if I cancel billing through Apple (iTunes) and then sign back into Pandora like heyy...I'm back. TIA!
