Ed Sheeran and Taylor Swift's creative communication spans a decade now.
The two are some of the most commercially successful songwriters of their generation, yet both are equally capable of enormous creative breadth.
The much-maligned – in some quarters – Ed Sheeran can move from grime and drill influences through to trop-pop and even Irish music.
Taylor, meanwhile, can move from wrought emotional conversation to neat, tucked pop anthems, adding and removing gloss at will.
Teased on socials, new song 'The Joker And The Queen' finds the pair relishing classicism, utilising form to craft a gentle delight.
It's an undiverting ear-worm, pleasant but definitely not distracting, sitting more in Sheeran's MOR vein than Taylor's recent reclamation work.
Coming straight from Ed Sheeran's metal-tastic BRITs performance alongside Bring Me The Horizon, it's a reminder of the songwriter's incredible thirst for new projects.
Difficult to dislike, 'The Joker And The Queen' doesn't feel like a key chapter for either artist, but it's certainly a worthy form of fan-service.
Tune in now.
