I can't say I've ever much cared for Sam's music, but I'd be a fool to pass judgement before I've heard it. Hoping they knock it out of the park - and that the rumors are true and we'll be getting the song itself tomorrow, vs. simply an artist confirmation.
Additionally: not that I think this would be a good route to take, given how disastrously the last attempt turned out, but I wonder if this is a quick final head fake and Smith and Ellie Goulding are in fact duet-ing it.
