You can listen to the full song on Tumblr.
Waiting patiently as possible for it to be released in the U.S. I tried purchasing it on iTunes UK, but it wouldn't let me. It sent me back to the U.S store.
For those in the UK here it is.. http://itunes.apple.com/gb/album/running-up-that-hill-deal/id550137693
I will post as soon as it's is available in the U.S.
