I think I would DIE if Adele did a cover of "The Way We Were."

One of my all-time favorites....
Also, even though "All I Ask" is one of my favorites, I don't want it as a single. She needs to release "Water Under the Bridge" and either end it, or release "Sweetest Devotion" as the fifth and final single.
If "Send My Love" starts slowing down on radio and the charts in the next few weeks, she should debut "Water Under the Bridge" at the VMAs and then at the Grammys in 2017, she can do this "amazing" performance of "When We Were Young" that she apparently had planned for last year before she switched songs (or "Hello," which is more likely).
And in regards to the Super Bowl, I'm pretty sure she'd be very verbal in ensuring that they don't push her to lip sync. She's not going to do it, and if they really want her that bad, it'll be under her terms, which means no lip syncing.
