I suspect it was at one point, hence all those early reports of ETIAW having a long intro.Should have just been part of Every Teardrop, instead of its own track.
I think it's sounds amazing. It feels like it's really building up for ETIAW. I wish they had added MMIX to the intro of ETIAW when it was released as a single. I don't know, I love the song much more now. It made me think of the Violet Hill intro, which really sets the mood while you haven't heard Chris sing a word.I suspect it was at one point, hence all those early reports of ETIAW having a long intro.
I've just attached all the interludes to their parents tracks with audio editing software so my version of MX is 11 songs long. MMIX makes ETIAW sound a bit better and more interesting, but doesn't add a whole lot.
Certainly undeserving of it's own track.
