I definitely saw a movie where it was used twice... I don't remember what I was watching...

Edit: I think I remember what it was! And the crazy part, it wasn't even a movie, it was an episode of Star wars: the clone wars (the animated show). They're only 25 minute episodes and they thought they'd just put it in twice anyway... It definitely made me chuckle, like "c'mon guys, really? Are you done?".

Then it was most certainly not first seen in LOTR, that shit is ancient.

You know that never having heard of something and assuming its the first time are two different things, right?

They do a better job of making it fit into the sound design nowadays instead of sticking out like a sore thumb like it did in older movies. Harder to catch.

Last thing I saw it in was the Baldur's Gate 3 intro.
