hi, I am from the US and I have a premium membership. I am listening to my music on my iPhone 8 I have IOS 11. I was listening to 2 song that I really liked but then i tried to replay then and it went gray. It won’t even let me click on it. I figured out I clicked a button that said I never want it to play again. It’s like a veto sign. I am confused, I didn’t want to click that. How do I undo it?
