Because Humans have used autotune too much.

[Liliana]

So what your saying is I should record my cats meowing and autotune it to an instrumental piece and post it on youtube?

Or I could record my dog howling, auto-tune...wait. Actually, I'd just need to cut it up and past it in various places, she's covered many notes for long periods of time. She howls too much.

But this would definitely be better, it's too silly.
