National guitarist Aaron Dessner used his Covid time to produce and co-write music with / for Michael Stipe and two Taylor Swift albums (plus two of her re-recordings of earlier albums).
With the latter, Dessner teamed up Swift and Iver for a song - whose title alludes me, but I remember it surprisingly not sucking and making Swift sound cooler than she actually probably is.
While I enjoy Matt Berninger, with "Weird Goodbyes", I'm not sure the song would work without Bon Iver. In somewhat true National style, the song is one beat and doesn't really expand upon that, but use the repetition to their advantage.
Honestly, upon first listen, the song didn't kick in with me until the second half. And it is growing on me.
