The OC...please read...I'm going mad!

Can anyone pleeease tell me the song sung in the last episode of series two? It was sung at the funeral and when Marissa shot Trey. I'd love it if anyone could help me out, I love the song and I can't find it unless I know what it's called! x x x

I think it's Imogen Heap - Hide and Seek , but I am not sure. You can try and download it.
