"He don't / she don't" em linguagem informal: Pode?

I don´t see any problem at all with it. I mean, it´s usually found in lyrics.

That's what you tell the cops Take a stand for a n-word Raise a hand for a n-word I solemnly swear he was with me all day Up to the judge, he know what I love Hell he could tell, she don't even budge Round and round we go Don't stop 'til I tell you so

Em várias músicas da cantora Britney Spears encontramos ela dizendo “he don’t” no lugar de “he doesn’t”. Uma dessa músicas é Amnesia. Logo no começo da música ela diz “if he wanna see me, he don’t even know it”. Na música He About To Lose Me, ela canta “I see that he don’t care”. Rihanna faz o mesmo ao cantar “got a girl at home, but he don’t care” na música Good Girl Gone Bad. Nessa mesma música ela ainda canta “all he’ll do is keep me at home”. As gramáticas mais exigentes dirão que o correto é “all he’ll is to keep me at home” ou “all he’ll do is keeping me at home”.
