"99% of the time the sentence is gramatically wrong " ? you should know it's just lyrics, even it is in chinese,there have somthing "strange" usage, i think you may be good at chinese,so for example, "我始终带着你爱的微笑 " it'a lyrics, we'll be puzzled if we understand it in chinese gramar, and "我的眼泪早已写成了诗" well,both of them are all lyrics,and is incorrect in gramar, but who care,it's a manner to show the art.
maybe there are some mistakes in my words, because i never learned gramer ,as the same with my chinese, so i just want to convey my personal viewpoint :)
