《good 4 u》是由奥利维亚·罗德里戈演唱的一首歌曲，由丹尼尔·尼格罗、奥利维亚·罗德里戈、海莉·威廉姆斯和乔希·法罗作词、作曲，于2021年5月14日以单曲形式发行，后收录至奥利维亚·罗德里戈的个人首张录音室专辑《SOUR》中。

奥利维亚·罗德里戈喜欢独自写歌，在一次洗澡时，她突然得到了《good 4 u》的灵感。而后奥利维亚认识了制作人同时也是她的创作伙伴丹尼尔·尼格罗后，两人共同完成了该曲的创作。通过讽刺的手法，奥利维亚·罗德里戈通过该曲想祝福她的前男友“一切安好”。奥利维亚认为将《good 4 u》这样一首表达愤怒的摇滚歌曲创作并发行出来是一件很酷的事。

Well good for you I guess you moved on really easily

You found a new girl and it only took a couple weeks

Remember when you said that you wanted to give me the world

And good for you I guess that you've been working on yourself

I guess that therapist I found for you she really helped

Now you can be a better man for your brand new girl

Well good for you

You look happy and healthy not me

If you ever cared to ask

Good for you

You're doing great out there without me baby

God I wish that I could do that

I've lost my mind

I've spent the night

Crying on the floor of my bathroom

But you're so unaffected I really don't get it

But I guess good for you

Well good for you I guess you're getting everything you want

You bought a new car and your career's really taking off

It's like we never even happened baby

What the f**k is up with that

And good for you it's like you never even met me

Remember when you swore to God I was the only

Person who ever got you

Well screw that and screw you

You will never have to hurt the way you know that I do

Well good for you

You look happy and healthy not me

If you ever cared to ask

Good for you

You're doing great out there without me baby

God I wish that I could do that

I've lost my mind

I've spent the night

Crying on the floor of my bathroom

But you're so unaffected I really don't get it

But I guess good for you

Maybe I'm too emotional

But your apathy's like a wound in salt

Maybe I'm too emotional

Or maybe you never cared at all

Maybe I'm too emotional

Your apathy's like a wound in salt

Maybe I'm too emotional

Or maybe you never cared at all

Well good for you

You look happy and healthy not me

If you ever cared to ask

Good for you

You're doing great out there without me baby

Like a d**n sociopath

I've lost my mind

I've spent the night

Crying on the floor of my bathroom

But you're so unaffected I really don't get it

But I guess good for you

Well good for you I guess you moved on really easily

《good 4 u》是一首带有帅气的朋克摇滚曲风的歌曲，具有快节奏和高音域，使得该曲在演唱时气息难以掌握。该曲浓浓的流行摇滚风也有着乐队Paramore和艾薇儿·拉维尼的感觉。该曲的风格和奥利维亚·罗德里格发行的前两首单曲《drivers license》《deja vu》几乎是在天秤两端，愤怒直白的歌词也让听众看到的奥利维亚风格的多样性。通过该曲，作为Z时代歌手的奥利维亚·罗德里格亦能收获千禧一代听众的心，透过原始、不加修饰的音乐，她将两代人青春期的共同经历联系在一起。

该曲MV由Petra Collins执导，并致敬了电影《詹妮弗的肉体》。MV开头，奥利维亚·罗德里戈被六部部三星折叠手机拍摄，她穿着白色白领衬衫，涂着红色唇膏。而后奥利维亚在体育馆中同六名啦啦操队员跳舞。奥利维亚在去杂货店买汽油之前戴上长长的黑色乳胶手套。她在一个属于她前男友的卧室中点火，同时大水淹没并冲毁了该房间。最后，奥利维亚跳入湖中游泳。

该曲被认为与乐队Paramore的歌曲《Misery Business》相似，后该曲创作者被加上了歌曲《Misery Business》的创作者海莉·威廉姆斯和乔希·法罗的名字。
