double negative = emphasis?

[keannu]

Do you frequently say ain't never to emphasize the negative meaning?
"Ain't never" means "I will never" not "I will". It is emphasis, right?
It's like "Don't shoot nobody" = "Never never shoot anybody"
Logically not+no = positive, but does it sometimes become positive or is it always emphasis of negative?


Halo

It's like I've been awakened
Every rule I had you breakin'
It's the risk that I'm takin'
I ain't never gonna shut you out​

Most native speakers would not use "ain't" at all.

Here is a great comprehensive discussion about why:

Actually, as some people in that thread suggest, quite a few native speakers do use it, but learners are recommended to avoid it. It is generally considered to be a sign of an uneducated speaker.

The use of a double negative for emphasis is also considered sub-standard and is also not recommended, but that is how it is used in your example, keannu.
