(Emotional) Vocal songs (with no lyrics)

I tend to really like pretty vocal songs. I'm not talking songs with lyrics (you know, like theme songs to Japanese RPGs), I'm talking about just songs with a woman singing notes.

Boy, that sounds like a really bad description. Not sure exactly what the term for that style would be. Choral songs? :-/

Anyway, I've found that these songs frequently contain a lot of emotion and are a joy to listen to. Here are some examples which should be familiar to those frequenting SotW or BSC:

Dreamfall - The Longest Journey Original Soundtrack - The Hospital Room:Get the Flash Player to play this audio file:
Chaos Legion - Blood Remains (Main Title): Get the Flash Player to play this audio file:
Gauntlet: Seven Sorrows - Unknown 14: Get the Flash Player to play this audio file:
Shadow Hearts 2 - The Fate: Get the Flash Player to play this audio file:
From BSC '05: Heroes of Might & Magic IV - Dirt (the second half)


And at the risk of getting suggestions of "regular" vocal songs, this could be expanded to songs like The Bird Chirps, I Sing from Tales of Legendia, Exceeding Love from Suikoden III, and Baba Yetu from Civilization IV, to name a few. Though they have words, they are are not typical Japanese vocal songs...hopefully people will understand what I mean. Forgive my inability to better describe what I'm talking about.

Jam it back in, in the dark.

Thanks for all the suggestions, everyone. I'll be sure to post again once I've listened to some of them (or if I think of any not yet mentioned).

There's nowhere I can't reach.
