Putting a mob head on soul soil makes the mob head make the mob's sounds.

The idea is simple. It would add a bit of a creepiness factor to the game. For all of the creepy builders out there.

Putting a mob head on soul soil will make the eyes of the mob head turn blue, the same blue as blue fire. And the mob head will emit the sounds the mob used to make, when not getting hurt. When just walking around.

Adding a redstone signal to the mob head on the soul soil, will make the mob head's eyes turn red, and the mob head will emit the sounds, it used to make when getting hurt.

It would add a lot of creepiness to a building. I really hope you like this idea, dear Mojang Team. I really would use this feature very often if it was a thing. I usually only post suggestions here when I got good feedback on Reddit, and I got a lot of upvotes when I posted that suggestion onto your Subreddit.
