it don`t matter no没有语法错误么?为什么歌里面可以这样唱?不应该是it doesn`t matter

为何But it don't matter no中don't不doesn't it doesn't matter.matter? it doesn't matter? it doesn't matter. 我经常看到有it don't matter ,有没有语法错误啊?和it doesn't matter 有什么区别啊? But it don't matter no It doesn't matter 还是 It is doesn't matter? It's doesn't matter还是It doesn't matter? "it doesn't really matter " it doesn't matter 英语 it doesn't really matter. it's doesn't matter!
