Hey!
I've been looking for this song by Enya (or at least she performs it) but I know very little about it. I think it's in spanish or latin, but it's definitely not in english. I THINK the title starts with a 'A' and it might be something like "adissium" "assidum" or somewhere along those line. The bad thing is, I'm not entirely sure of any of it.
If you have any idea what song this might be, please answer!

Adiemus - Enya sings backup... You can find the song on the Pure Moods CD
