《It'sComplicated》是ADaytoRemember演唱的一首英文歌曲，这首歌收录在《WhatSeparatesMeFromYou》专辑中。
《Complicated》的MV拍摄于美国洛杉矶的鹰岩广场（为期两天），MV导演由The Malloys担任 。在MV开头，艾薇儿·拉维尼踏着滑板朝自己的乐队走来，与他们商量着是否要去商场搞破坏，这个提议得到了乐队成员的一致认同。于是，艾薇儿·拉维尼与乐队成员一同前往商场，化身“不良少年”在不同的娱乐场所内大搞破坏，骚扰顾客和工作人员。同时，MV也拍摄了艾薇儿·拉维尼与自己的乐队在运动场地滑滑板、弹吉他、唱歌的场景 。
英文
Uh huh yeah
Life's like this
Uh huh, uh huh
That's the way it is
'Cause life's like this
Uh huh, uh huh
That's the way it is
Chill out, what you yellin' for?
Lay back, it's all been done before
And if, you could only let it be
You will see
I like, you the way you are
When we're drivin' in your car
And you're, talkin' to me one on one
But you become
Somebody else
'Round everyone else
Your watchin' your back
Like you can't relax
You tryin' to be cool
You look like a fool to me
Tell me
Why the hell you have to go and make things so complicated?
I see the way you're, actin' like you're somebody else
Gets me frustrated
Life's like this you
You fall and you crawl and you break
And you take what you get, and you turn it into
Honestly, you promised me
I'm never gonna find you fake it
No no no
You come over unannounced
Dressed up, like you're somethin' else
Where you are ain't where it's at you see
You're makin' me
Laugh out, when you strike a pose
Take off, all your preppy clothes
You know, you're not foolin' anyone
When you become
Somebody else
'Round everyone else
Your watchin' your back
Like you can't relax
You tryin' to be cool
You look like a fool to me
Tell me
Why'd you have to go and make things so complicated?
I see the way you're actin' like you're somebody else
Gets me frustrated
Life's like this you
You fall and you crawl and you break
And you take what you get, and you turn it into
Honestly, you promised me
I'm never gonna find you fake it
No no no
(No no no)
No no
(No no no)
No no
(No no no)
No no
Ooh, chill out, what you yellin' for?
Lay back, it's all been done before
And if you could only let it be
You will see
Somebody else
'Round everyone else
Your watchin' your back
Like you can't relax
You tryin' to be cool
You look like a fool to me
Tell me
Why'd you have to go and make things so complicated?
I see the way you're actin' like you're somebody else
Gets me frustrated
Life's like this, you
You fall and you crawl and you break
And you take what you get, and you turn it into
Honestly, you promised me
I'm never gonna find you fake it
No no
Why'd you have to go and make things so complicated?
(Yea yea)
I see the way you're actin' like you're somebody else
Gets me frustrated
Life's like this you
You fall and you crawl and you break
And you take what you get, and you turn it into
Honestly, you promised me
I'm never gonna find you fake it
No no no
《Complicated》是一首朗朗上口的吉他弹奏歌曲 ，歌词内容描写的是一个“虚伪”的人。在音乐上，艾薇儿在歌曲中的歌声稚嫩、可爱，唱出了她早期的摇滚乐风格，歌曲简谱主要由F大调构成 。
该歌曲由艾薇儿与The Matrix制作团队创作 ，歌曲的创作时间只用了一晚上。在写完歌曲后，The Matrix就发现这首歌的歌词并不吸引人，于是就回到工作室里重写了这首歌曲 ，而这首歌曲的名字正是取自歌曲中的一句歌词：“为什么你要把事情搞得这么复杂？”。当艾薇团队负责人之一的Josh Sarubin听到这首歌后，他就把歌曲介绍给l.a reid听，l.a reid在听完后，开始全力支持艾薇儿与The Matrix合作歌曲，并强烈要求把这首歌作为专辑的首单发行 。而艾薇儿则在采访时表示，她创作《Complicated》并不是为了特别描写某一个人，而是想要表达生活中的一些“两面派朋友”和虚伪的人际关系 。
