Grah! I KNOW this song from SOMEWHER! I think it might have been used in movie commercials or something?
YouTube - Ah ! My Goddess ! - Absolution (http://youtube.com/watch?v=8SD7uwZvaEY)

If anyone knows what this is called, please tell me?
And I checked, it's not called Absolution

Ah yes... the song from the old Zales Commercial when the diamonds are being placed on the silhouettes?
Palladio: I. Allegretto

Ah! Thank you very much. =]

The original was Lux Aeterna "the eternal light" by clint mansell... http://en.wikipedia.org/wiki/Lux_Aeterna_%28Requiem_for_a_Dream%29 (WIKIPIDA) also known widely as (Requiem For A Dream)

The original takes forever (1.5 mins) to get to the goood stuff in the beginning. The mix you found is pretty good too.
