"Treacherous (Taylor's Version)" is the third track of Taylor's second re-recorded album, Red, that was written by Taylor Swift and produced by Dan Willson.

Lyrically, the song expresses the feelings in a relationship which Taylor knows that is not really good for her — that relationship is treacherous. Some of the lines in this song were the first time that Taylor ever sang about having something with sexual undertones.

Some people assume that Harry Styles inspired the song, but others think that the song is about John Mayer or Jake Gyllenhaal.

Taylor confirmed that the song is about the same person as the person in the song "I Knew You Were Trouble," so the song is probably about Harry Styles.

Lyrics-

Put your lips close to mine
As long as they don't touch
Out of focus, eye to eye
'Til the gravity's too much
And I'll do anything you say
If you say it with your hands
And I'd be smart to walk away
But you're quicksand

This slope is treacherous
This path is reckless
This slope is treacherous
And I-I-I like it

I can't decide if it's a choice
Getting swept away
I hear the sound of my own voice
Asking you to stay
All we are is skin and bone
Trained to get along
Forever going with the flow
But you're friction

This slope is treacherous
This path is reckless
This slope is treacherous
I, I, I like it (Oh)

Two headlights shine through the sleepless night
And I will get you, get you alone
Your name has echoed through my mind
And I just think you should, think you should know
That nothing safe is worth the drive
And I would follow you, follow you home
I'll follow you, follow you home

This hope is treacherous
This daydream is dangerous
This hope is treacherous
I-I-I, I-I-I, I-I-I

Two headlights shine through the sleepless night
And I will get you, get you alone
Your name has echoed through my mind
And I just think you should, think you should know
That nothing safe is worth the drive
And I would follow you, follow you home
I'll follow you, follow you home
I'll follow you, follow you home
I'll follow you, follow you home

This slope is treacherous
I-I-I like it
