In songs, nobody uses them anymore, they still use the s for example "she says", but for negations, they all say "she don't".

Are these english forms fading from spoken english?

poor dem

i doesn't know. does you think so?

It doesn't seem like they're used much, does it?

Ugh I hope not I hate it when people say "she/he don't" in songs... its like.. did u not pay attention in 2nd grade basic grammar?
