I haven't got my official CD yet, but I've found an album download for the karaoke versions, and... it seems that Israel has gone back to the earlier, leaked version of the song for some reason?
In other words, rather than the song starting with around 23 seconds of Netta showing off her looper before the first verse, it instead has the 14-second instrumental intro from the leak. I'm not complaining, since I didn't really have a strong preference between the two versions, but I'm curious as to why. Perhaps there were issues with getting permission for the looper after all?
Also, despite the intro being 9 seconds shorter, the song is only 2 seconds shorter on the whole. So there's now an extra 7 seconds somewhere, I guess? Though I haven't found where yet (EDIT: Okay, now I have. The chorus before the bridge now repeats for an extra two bars before the bridge comes in).
