Yeah, it's not a bad tune. It serves a purpose, and anything to do with space is super cool in my book. I had assumed this was part of a full album, but actually it seems maybe it isn't.
I was getting really grumpy about the track only appearing on iTunes, but I'm guessing it may turn up elsewhere eventually. If not I'll be able to find it somewhere I'm sure. I don't want to get into a big rant about Apple, but on top of the exclusive thing that film is a bit cringey to me. Like hey, we're all just chilled out groovy artists hanging out and being arty and so happy that Apple is in their lives making everything amazing, a bit like space does. Ick. I know it's business and all that - just don't pretend it isn't.
