… Walk on through a red parade and refuse to make amends
It cuts deep through our ground and makes us forget all common sense

The song is comparing their lover to a remedy and clarity, it must mean the lover is a cure for the person's sadness or negative feelings.

The use of the word "insanity" is a hyperbole of how their love might seem to someone evaluating the love from the outside, making it seem extremely toxic/unhealthy.  

The truth is
The truth is all about you
And your honest point of view

"The truth" is repeated six times, stressing Jase's point about the true definition of "the truth". Irony is included within this repetition, using the same phrase to both explain and describe the exact same thing. He is telling the truth about the truth.

A metaphor within these lyrics would be "The truth is all about you, and your honest point of view". It compares the truth and "you", showing how the truth can relate to whoever "you" might be.

At least I can say that I've tried
To tell you I'm sorry for breaking your heart
But it don't matter, it clearly doesn't tear you apart anymore

"I must've called a thousand times" is a hyperbole which shows Adele's hopelessness and aspiration for something.
"It clearly doesn't tear you apart" is an idiom that means something doesn't bother you. This shows that Adele is possibly in a one-sided love because someone does not feel the same way about her as she does with them.

So I sneak out to the garden to see you
We keep quiet, 'cause we're dead if they knew
So close your eyes
Escape this town for a little while, oh oh

'Cause you were Romeo, I was a scarlet letter
And my daddy said, "Stay away from Juliet"
But you were everything to me
I was beggin' you, "Please don't go, " and I said"

Repetition

Hyperbole
Romeo and Juliet aren't literally dead if they get caught its an exaggeration to show how risky they are being and how much they are willing to risk for each other.

Metaphor
She is referring to herself as a scarlet letter. A scarlet letter symbolizes shame, so she is saying she is seen as not worthy and shameful in the eyes of many.

Hyperbole

-Olivia

I said, ooh, I'm blinded by the lights
...
I said, ooh, I'm drowning in the night
Oh, when I'm like this, you're the one I trust
Hey, hey, hey

When he sings, "Sin City's cold and empty" he's talking about a metaphorical place that only he can go to where no one could ever know what he's done. 
The excerpt, "I can't see clearly when you're gone" is personification because he feels he loses focus of himself without whomever he's talking about. 
"I'm drowning in the night" is also personification because he feels like he's being over taken by darkness, and feels he can't live without the person he's talking about.

Turn me up when you feel low
This melody was meant for you
Just sing along to my stereo
Let's go!

The line "My hearts a stereo" is a Metaphor because he is comparing himself to a metaphor. Also the line "Let's Go!" is a onomatopoeia because it makes a sound.

I'm bulletproof, nothing to lose

Ricochet, you take your aim

Fire away, fire away

You shoot me down, but I won't fall

I am titanium

Repetition- The artist says, "Fire away, Fire away" is an example of repetition and is trying to show how important this saying is to the song artist. The saying fire away means that they are ready for whatever comes their way. 

Metaphor- The artist says in the song, "I am titanium" is a metaphor because it is comparing the person with a metal to convey that they are strong and nothing can hurt them and take them down. 

Irony- The phrase in the song, "you shoot me down, but I won't fall" is irony because if you are shot down you will obviously fall, but the artist uses this phrase to show that they can stand up to anything. 

When the morning comes
When we see what we've become
In the cold light of day we're a flame in the wind
Not the fire that we've begun
Every argument, every word we can't take back
'Cause with the all that has happened
I think that we both know the way that this story ends

"I want you to be happier" Is an example of repitition. It shows that they want someone to be happier. By using it repetedly shows that this means a lot to them or who they are reffering to is very close to them.

"we're a flame in the wind" This is a metaphor. They are saying that them and whoever else they are reffering to is the flame or the fire in the wind. This is saying that their relationship is just going away and is either not like it used to be or is just gone, such as the flame or fire blowing out in the wind.

I know my friends and I
Would probably turn and run

When the song says, "Dead ends in my mind" It is showing an example of a metaphor. It is comparing a dead-end or stuck in a box to their mind. He is saying that his mind has hit a wall and he is unable to move forward from it. 
Another Metaphor is when the song says, "Love's seeping from the guns" because it is comparing the love to ammo in a gun.

Yeah, we're happy, free, confused and lonely at the same time
It's miserable and magical, oh yeah


When Taylor Swift says "Miserable and Magical" this is a Alliteration because the same sound is occurring twice.

When Taylor Swift says "happy, free, confused and lonely" this would be an example Imagery because she is describing something using sense.

When Taylor Swift says "To fall in live with strangers"  this is an example of Hyperbole because it is an exaggerated. 

You held me down, but I got up (hey)
Already brushing off the dust
You hear my voice, you hear that sound
Like thunder, gonna shake the ground
You held me down, but I got up (hey)
Get ready 'cause I've had enough
I see it all, I see it now

I got the eye of the tiger, a fighter
Dancing through the fire
'Cause I am a champion, and you're gonna hear me roar
Louder, louder than a lion

"Floatin' like a butterfly" is a simile, comparing her to a butterfly. She is saying that she is free and can do whatever she wants, rather than someone else controlling her.

"You're gonna hear me roar louder, louder than a lion" is a metaphor comparing he voice to that of a lion. She means that now that she isn't being controlled, she wants her voice that was previously suppressed to be heard by others.

The repetition of the word "louder" emphasizes that she is going to get her voice to be heard, so it is "louder than a lion," especially since lions have extremely loud roars.

'Cause baby, you're a firework

Come on, show 'em what you're worth

Make 'em go, oh

As you shoot across the sky

Baby, you're a firework

simile. The night to the forth of July is compared because the night is supposed to be exciting and special with reason to celebrate just like The Forth of July. 

metaphor. Baby you're a firework is saying that the "baby" is a firework so this suggests that person is "striking" in some way or is some kind of acknowledgeable/important person.

The hyperbole shoot across the sky isn't meant to literally shoot across the sky but rather do something so great that it can be recognized by all, like a shooting star.

The Onomatopoeia "oh" is said in a tone that implies that someone is being impressed.

"Ooh, you got it in you
Ooh, you got it in you"
- he uses repetition to emphasize how important it is to believe in yourself, and there is a better chance that you will listen if he says it more than once.

"When the lights go out and leave you standing in the dark"
- this metaphor describes how we can feel when all hope is gone, we feel lost like trying to find our way through a dark room

"No one ever told you this would be so hard"
- BANNERS uses hyperbole to show how hard life can be sometimes, that almost nobody seems to understand it prior to our experiences

"I know you think your fire is burning out
But I still see you shining through
You got it in you"
- BANNERS' diction helps convey his message. by pausing before saying you got it in you, he emphasizes how meaningful it is. Also, his choice to use so many metaphors conveys that sometimes life is hard to put into words and that it can seem bigger than reality

notes:
(lol I did a lot but I just couldn't choose because I love all of these lyrics)
(also, the lyrics are in the order they go in through the song)

And I think I need your love, I don't need no one selfish
Wonder if I give this girl my heart, could she help it?
And you know she's an angel if you let her tell it
Baby hot as hell, she got kicked out of heaven

The phrase "Devil in a dress, angel in some Nike Airs" is a metaphor and allusion. Rod Wave uses the word "Devil" to connect to the girl the song is about.  

It is allusion because he uses the term "devil"  to describe this girl that he fell in love with and a devil is associated with being evil,  malicious, and devious. He is basically saying that this girl he likes is evil because she made him fall for her and it's almost like she tricked him and manipulated him and now he is attached to her.

It is also Irony because he uses "Devil" and "Angel" to describe the same person and they are polar opposites.

"Baby hot as hell" is a simile, comparing the girl and hell. It means that the girl is very attractive.

"she got kicked out of heaven" is a idiom which basically means she came from heaven because she is so perfect but came down to earth because she was "kicked out"
