If Million Reasons is the second single she can go ahead and end the era right away tbh. That song will go nowhere and will capture literally nobody's attention. Very forgettable too and anyone saying it's going to make people buy the album is obviously forgetting that sales are dead and she needs to establish herself as a streaming artist if she wants to succeed. Her next single needs to be upbeat for everyone saying a hit doesn't need to be upbeat to smash, there's like one slow hit for every ten ones so obviously having an upbeat single increases her chances of having a hit.
