Don't need no...听歌的时候经常听到这种双重否定,但根据上下文意思好像仍旧表示否定含义,困惑中……原句：Don't need no fortune teller to know where my lucky love belongs.(Joyride-Roxetee)

这是一种不规范的说法．不能算错误．至今有些非洲裔美国人还这么说．严格来说是不符合语法的．遇到这种情况,就把后一个否定去掉．
eg, we don'd need no education, we don't need no thought control. from Pink Floyd, Another brick on the wall.
