是美国性感女神Beyonce 《IAm...Sasha Fierce》中的一首主打曲，并在2008年10月作为《I Am...》碟中的首支单曲，并与《Sasha Fierce》碟中的《Single Ladies (Put a Ring On It)》并行发行。

歌曲在小字组内横跨2个八度，高音很高，低音很低，伴奏缓慢抒情，高潮部分碧昂斯强有力地唱出了歌曲的灵魂：“如果我是男孩儿，我也可以和喜欢的人混在一起，我也可以毫无顾忌的去泡妞”，讲述了当你失去你爱的人的时候，男孩儿们应该怎样去好好爱一个女人。

《I Am...Sasha Fierce》是碧昂丝第三张个人录音室专辑。在这张双碟专辑中，碧昂丝分饰情歌本尊碧昂丝，和舞台上动感的虚拟莎夏(Sasha Fierce)，打破传统发行单曲模式，每次发行两首单曲，上演抒情碧昂丝与动感莎夏的对手戏。

由碧昂丝身份演唱的《I Am...》大胆启用新锐制作Toby Gad(Donna Summer、Natasa Bedingfield)掌控第一主打“If I Were A Boy”，以女人的角度审视男人对爱的态度，感人催泪之演绎获得乐迷广大回响，覆盖大量钢琴和弦乐柔美交织的“Halo”，《I Am…》深深感受碧昂丝光鲜亮丽背后小女人的一面，对爱的渴望、对人的省思、对生活的认真，展现新都会女性自信成熟的态势。
