+ SO MANY MORE, too much too list. :P

You have them on like every single or something, and there are more remix albums with (acoustic) orchestra versions. You even have a lot of fan made orchestra (I know that there's even a Rule (Orchestra) version.

ALL of them in alphabetical order... I included Acoustic Orchestra versions if they had prominent strings. The HARMONY versions are included even though they're instrumental. I didn't include AO versions as included in nonstop megamixes since that woulda been redundant.

I didn't include the Princess China Music Orchestra album since it's not a traditional western Orchestra sound, but if you count that, then there's that too.

This does include everything from remix albums AND singles that qualify as "orchestra" but it does NOT count Acoustic versions. (for example, Moments "Acoustic Piano version" and Endless sorrow "Acoustic Orchestra version" aren't there since they're just piano & acoustic guitar respectively.)
