747 versions:

[Negamuse]

Well, this is the first time I've heard the full length 747. Yeah, I know.

I can kind of hear it... not so much the "magic" thing, but earlier 1:30-1:40 ish it washes in and out, and then throughout. Sounds like one of those big reverse huge reverbs on his vocal like at the beginning of the first word he sings in Kind of Magic, and in One Vision I think as well? But it never hits the actual vocal part of it, so maybe they pingpong it in and out if that's what it is.

No idea what that piano sample at the end's from. Wish I knew.
