What is your favorite emotionally powerful music?

I'm looking for music that would be considered "emotionally powerful". Music that brings tears to your eyes, a smile to your face, heartache, long forgotten memories. I'm looking for music you can get immersed in, music where you can close your eyes and 'live' in the moment of the song. Can be from any genre, but I've found that instrumental and soundtracks quite often are the best. What's your favorite?
