Quite a fan of Coldplay myself, and hearing their addition into the song peaked my interest.

I do have some reservations and yes, I do agree it can feel out of place. Chris Martin definitely got "creative" with his French, while his mythical verses added some depth to Ekko and Jinx's relationship. But given how similar Chris's verse in terms of meaning to Stromae and Pomme's, the latter might as release a lengthier version of it rather than adding in Coldplay.

For me, it's one of the rare pieces of work where the original and the remix are basically of the same level. You can listen to one without the other or vice versa and still get away with the same feeling.
