VII's soundtrack is great but there is one song that never gets as much love as it deserves.

(SPOILER)

We all remember that first time we found Mideel...when we found our hero. First his mind and will were broken and then his body went too. Discovering Cloud in that pitiful, barely-alive state was really jarring. To cap it all off, Tifa's reaction and vowing to stay by his side made it hit even harder.

This song and that sad little noise that I think is supposed to be Cloud wheezing or a machine breathing for him, as well as the way his head slowly rises then inevitably falls down again, was just incredibly tragic for the time.
