For obvious reasons it's not getting too much of a look in today, but I think it's a really strong single. Always a bit of a worry that the new tracks on a Greatest Hits won't be up to much, so this is reassuring in terms of whatever happens next.
What a knockout track! They really have pivoted back to being a pop group (it feels like a pop track to me), with few pretensions to anything else, and are all the better for it.
They also seem to be having fun with it all again.
