Ambient sounds bugged?

https://minecraft.gamepedia.com/Ambience

Track 18 and 19 on the gamepedia (which I've never heard before and I've played since 2013, so I assume they are new) randomly played in the background while I was roaming the overworld/forests in broad daylight. I understand that it must have been triggered by shadows from the trees, but it's still completely out of place. Track 18 sounds like something that would be heard around a mineshaft (or a smithy?) and track 19 is just straight up 'Predator' which I guess makes sense but it still feels really out of place if it's intentional.
