I don't think it will be dance actually...she may be working with dance producers but from what I've seen, in every picture, they've had acoustic instruments. Sure, this may be a route some dance producers take to make a great dance song - starting raw. But EVERY pic?? It definitely seems like they're all collaborating on something different, or new for all of them and that's why I think this might be going in a classic rock / throwback / real-instrument / vocal direction
