回答：这些句子没有错误，语法中这种用法叫做虚拟语气。关于wish引导的虚拟语气的用法详细如下：虚拟语气 一、概念 它是一种动词形式，表示说话人的某种假设、愿望、怀疑、猜测、建议等含义。二、语法结构 wish结构       与..事实相反               过去                Had done       现在                Were/did       将来                Would          备注：可转换为其他形式。      例句：            He wish all hadn't happened(与过去事实相反)            他希望这一切都没有发生过            I wish I were a bird.(与现在事实相反)            我希望我是一只小鸟            I wish I would be rich in the future.(与将来事实相反)            我希望我将来很富有。以上只是一种形式的虚拟语气，关于更多的虚拟语气情况请查询相关资料。（不过近年来这个语法点在考试中逐渐被淡化，不需研究太透彻，中学时代只要了解几种常见的情况就可以了，大学里还要具体讨论）=========================================================下面再分析一下歌词中的句子：Sometimes I wish I were an angel有时候我希望我是一个天使（注意：实际上这种愿望是永远不能实现的）sometimes I wish I were you有时候我希望我是一个天使（注意：实际上这种愿望也永远不能实现的，我就是我，怎么可能是你呢？）注意：此用法中的wish不能换成hope。
