Hide & Seek

So it just happened...I found one of those songs that, upon first hearing it, you instantly know its like one of the best songs you've ever heard. So the last time this happened for me was with Damien Rice's The Blower's Daughter. Now it's Imogen Heap's Hide and Seek. It's amazing for so many reasons, first of which is that there are no instruments in the entire song, just layers of her voice. It's amazingly beautiful and innovative and many other words I can't seem to think of at the moment.
