I've noticed that in some cases music artists (and maybe someone else too) use conjugation that is technically wrong, however it's obviously done on purpose. Here are some examples from The Weeknd - Six Feet Under: "She don't get emotional", "She don't depend on anybody", "She lick it up"..
I guess that might be for rhythmical purposes, but I would like to find out if it changes a sense somehow or some feeling. Because if I try to do that thing in my language it will not sound native.
Thanks in advance!
