It don't matter

I know "don't" instead of "doesn't" is a feature of African American English, but I'd like to know what other dialects of kinds of people use it as well in the USA or the UK or whatever, or in what regions. I'd like to know about the double negatives usage as well, not considering AAVE.
I hear those features really a lot in songs, from white people (for example Christina Aguilera), so I wonder. Thanks.

It's mostly a matter of style when it is used in songs. Also, the second part of the word "dosen't" don't sing very well. ;)

''That don't impress me much'' (Shania Twain from Canada)

BTW there are cases when a triple negative is used, eg: "I didn't go to no London never" (G Wells, "The Invisible Man")
