Help!

[tinypinkstar]

Does any one know if I can buy an mp3 of Astronaut anywhere without having to buy the entire album (I plan on rushing out and bying the physical copy next week, and the pre-order where you get access to the whole album on mp3 at the same time isn't really any good to me as I'm in the UK). I'm DJing at a dark cabaret night tomorrow, and I'd really like to play it!

Sorry if this is a very obvious thing, but I'm feeling a bit stupid right now - got off a delayed plane in the early hours of this morning!
Thanks C
