Austin Swift and Taylor Swift attend the 49th Annual Academy of Country Music Awards at the MGM Grand Garden Arena on April 6, 2014 in Las Vegas.

Check out some of the best ones.

Jack Leopards & the Dolphin Club's extremely stripped-back cover of Taylor Swift's "Look What You Made Me Do," featured in a recent episode of Killing Eve, is haunting.

But almost as spooky is the mystery surrounding the origins of the song.

We know the song's creator, Taylor Swift, was "VERY STOKED" to hear the track credited to producers Jack Antonoff and Nils Sjöberg.

There is a shroud of mystery surrounding the track, which a lot of fans think features vocals from Taylor's younger brother, Austin, with production linked to the pseudonym previously attributed to Taylor in disguise (Sjöberg) on the co-write of the 2016 track "This Is What You Came For" for Calvin Harris and Rihanna.

Even more interesting is the Swiftie theory that the singer might be exacting some sweet revenge on former Big Machine boss Scott Borchetta and his partner, Scooter Braun, by releasing a cover version of a song from her back catalog that the two men now jointly own.

Fans also pointed out that 28-year-old Austin formerly used "The Dolphin Club" as his Twitter handle, based on a childhood photo of him wearing a shirt with that title on it, which, wait for it, he's wearing in the cover art for the song.

Check out the best fan theories about the cover below.
