In what initially seemed like a joke but has now become gloriously real, Ryan Adams has spent the past few days recording a full-length cover album of Taylor Swift’s 1989. He’s almost halfway through the tracklist by now, and he’s been keeping us up to speed on his progress with regular social media updates and occasional previews. Last night he was working on “Bad Blood” and “Wildest Dreams,” which he called his “fav section” of the album. You watch a couple of previews of the finished version of “Bad Blood” below — most of the songs are supposedly in the style of the Smiths, but this one is more straight Ryan Adams, and he calls it a Heartbreaker sounding version.
