Where is the 5.1 mix from Monsters Inc?

[MacinMan]

Hey all,

I did some searching earlier on this, and then look through my discs, and couldn't find a solid answer.

I own the 4K release of Monsters Inc. I've owned this movie since it's initial release on DVD, then upgraded to the Initial Blu-ray release, and now have the 4k release. Where is the 5.1 sound track that cuts out the vocals and is just the surround mix. I know the DVD had it, I can't remember if the Initial Blu-ray had it, or not. Can't find it anywhere on the 4k disc, the standard BD, or bonus features disc. Did it get cut out, or did they hid it?

Thanks
