Khalid's music fits into the contemporary R&B genre along with the pop genre. This song fits better into the R&B genre because of how Khalid controls his voice, this is a big identifying factor of what genre it fits into. This song was on Khalid's first album and since then he has created another album that still fits into the contemporary R&B genre, but does explore a different side of his music.
The song coaster is a metaphor for how some people chose to move through their life. "As time passes, I feel so low" is the very first line of the song and is starting it out on a sadder note. The beat of the song also starts off low and as the song progresses the beat starts to pick up pace. "So I'll be coasting, roller-coasting" is Khalid's way of dealing with his emotions which is how many chose to process their own emotions. Roller coaster is being used as a metaphor to explain how many tend to process their emotions after a breakup or when something unwanted happens, which includes lots of ups and downs with some curves thrown in. This method allows for time to process what happened before making rash decisions. Many people tend to jump to conclusions and by coasting through the process of acceptance may help some stop making such rash decisions right away when something bad or inconvenient happens. "You weren't the one for me" "So don't come back to me, no" "No, don't come back to me" is the outro of the song and unlike the beginning of the song it shows that he has finally accepted what has happened and is moving on. A main take away from this song is that even though it may seem like the end of the world when something bad happens, if you wait it out and coast through the process it will eventually no longer matter.
[Verse 1]
Searchin' for pieces, covering up the hole
I'll fight for your love, I'll fight for your soul
I'll throw all of my cares away for you
I'll be there to wait for you
Maybe you weren't the one for me
But deep down I wanted you to be
I'll still see you in my dreams
All the things that I did for you, just wasn't it for you
[Chorus]
So I'll be coasting, roller-coasting
Through my emotion
I will be coasting, roller-coasting
I'm hoping that you'll come back to me
[Verse 2]
Moving on seems harder to do
When the one that you love moves faster than you
I gave you my all, I showed the proof of your lies
And you weren't worth it, you don't deserve me
As time passes I'm feeling high
You're not the one I'm thinking of tonight
I may not be over you, but I'll try inside
I'm feeling better now, finally feeling special now, oh
[Chorus]
Coasting, roller-coasting
In my emotions, oh
I'll be coasting, roller-coasting
I noticed you weren't the one for me
[Outro]
You weren't the one for me
You weren't the one for me
You weren't the one for me
You weren't the one for me
Weren't the one for me
You weren't the one
You weren't the one for me
So don't come back to me, no
No, don't come back to me, no
No, don't come back to me
No, don't come back to me, no
No, don't come back to me
You weren't the one for me
You weren't the one for me
You weren't the one for me
You weren't the one for me
