（韓文歌詞）
Yeah this is Labo again
Gonna hit you with that real st this time
Up and down (Up and down)
You keep on grinding (Grinding)
I'm feeling like I'm on top of the world right now
Verse 1:
Day by day you keep on giving me reasons
Why you shouldn't be denied
Yeah I been feeling off my game
Now I'm in the zone again, now it's a battle
Can't keep up with the ups and downs
So many memories I ain't got no time to drown
Now it's a battle, can't get it back again
No room for error, now I'm back in the swing
Chorus:
Up and down (Up and down)
You keep on grinding (Grinding)
I'm feeling like I'm on top of the world right now
Yeah they screaming out my name
We getting it popping like it's twenty fifteen
Verse 2:
Myself, a motherfking star in the making
Everyday I'm getting stronger, never backing down
Got my eyes on the prize, never letting go
Going up and down, feeling like I'm on top of the world right now
Chorus:
Up and down (Up and down)
You keep on grinding (Grinding)
I'm feeling like I'm on top of the world right now
Yeah they screaming out my name
We getting it popping like it's twenty fifteen
Bridge:
When the night falls and the lights dimming
You gon' see a rising star in the making
Just like a shooting star, it ain't even a game
You gon' feel my vibe, we gonna ride it out, oh my god
Chorus: (Repeats)
Yeah they screaming out my name (Oh my god)
We getting it popping like it's twenty fifteen (Yeah they screaming)
（中文歌詞）
Yeah，this is Labo again，再次給你帶來真實的東西。
Up and Down (Up and Down)，你讓我不斷掙扎。
You keep on grinding，我感覺我現在就像站在世界之巔。
Day by day，你不斷給我理由，為什麼你不應該被否認。
Yeah，我現在感覺我已經失去了比賽，現在我再次進入區域，現在又是一場戰鬥。
無法跟上起伏不定，這么多回憶，我沒有時間沉溺其中。現在又是一場戰鬥，無法重新開始。沒有錯誤的空間，我現在回到正常狀態。
Verse 2:我自己，一個正在形成的明星。每天我都變得更強大，從不退縮。我的目標很明確，從不放手。上下起伏，感覺我現在站在世界之巔。Chorus重複：Up and Down (Up and Down)，你讓我不斷掙扎。You keep on grinding，我感覺我現在就像站在世界之巔。Yeah他們高呼我的名字我們像這樣瘋狂一樣流行起來就像2015年一樣。Bridge：當夜幕降臨，燈光暗淡時你會看到一個正在崛起的明星就像一顆流星一樣，這不是一場遊戲你會感受到我的氣息，我們會騎乘它，喔我的上帝！Chorus重複：Yeah他們高呼我的名字我們像這樣瘋狂一樣流行起來就像2015年一樣。
