Good ol' "
causing much mayhem, dropping drama" probably needs no presentation.
I'm afraid I don't know which libraries, but some stuff to watch for:
Some of Meguro stuff, like the French vocals in
Persona 3's "201 Changing Season".
I'm under the impression much of

Toshikazu Tanaka loves his canned voices too.
This is more of a question but I swear I've heard
NieR's "2.01 The Dark Colossus Destroys All" chorus somewhere else, anybody knows? (classic?)
