旋律性
歌曲的曲调是否清晰易记，是否遵循了明确的音乐模式。旋律性强的歌曲一般具有清晰、令人难忘的器乐或声线。
不插电
衡量一首歌曲对不插电乐器（例如钢琴、吉他、小提琴、鼓、萨克斯）而非电子或数字合成的依赖程度
Valence
通过歌曲的和声和节奏成分，传达的音乐积极性或情感基调。高情感值与幸福、兴奋和愉悦的感觉相对应，而低情感值则与悲伤、愤怒或忧郁有关。
舞蹈性
综合各种因素，包括节奏的稳定性、节奏模式和节拍重点，来确定一首歌曲是否适合跳舞。一首“适合跳舞”的歌曲可能具有稳定的节奏、重复的音乐结构和强烈的重拍。
能量
曲目的感知强度，可能受节奏、动态和音乐紧凑程度的影响。一首高能量的歌曲可能节奏欢快、乐器编配丰富，而一首低能量的歌曲则可能音乐编配简洁、节奏较慢。
歌词
Hey!, Kali baby!
(She got a backpack!)
And a lunch pail too
Cheatin' when I'm sitting next to you
(She got a backpack)
And I got a ruler for her too
And I'm bout to take her back to school
(She got a backpack!)
And a lunch pail too
And milk could do her body good too
(She got a backpack)
And I got a ruler for her too
And I'm about to take her back to school
Like this!
I can tell she got that thing by the way that she walking
Love that ding-a-ling by the way that she talking
Baby got them goodies, think she wanna do me
She's a floozy, oozy wanna give it to me
She got a jack-in-the box, plus she a fox, might jump right off
If I get to toss, not gonna talk, lights come right off
She know I'm Kali baby maybe its unfair
I don't care, I just wanna lay in her hair
Give me than number one rhyme-y voo on the after set
I ain't seen one to stunt ya wonder if it happened as of yet
Her bubble, gets me in trouble
You can call it two XL, imma call it double (oh yeah!)
Her backpack two pack, eject some, she got me erect some
Now I just expect some
Your body's inviting me to a fight that we'll both like
We'll end the night in the right light if I spoke right
(Baby!)
(She got a backpack!)
And a lunch pail too
Cheatin' when I'm sitting next to you
(She got a backpack)
And I got a ruler for her too
And I'm bout to take her back to school
(She got a backpack!)
And a lunch pail too
And milk could do her body good too
(She got a backpack)
And I got a ruler for her too
And I'm about to take her back to school
Like this!
Her backpack full of school supplies
(Whoo!) Her thighs make me scoop her
Back end round like a tuba
Got a trunk on her
Front keeps me wantin' her
Mad at her for that
Matter of fact, I need to have it in the back
Attack it in the sack
Don't know how to act when around ya
She gimme that look like I'm bout to clown ya
I hound ya, for a piece of that
How's about a squeeze on that
I'm easy like Sunday morning
I'll give up my cheese for that
Thick Ms. Krizz is the pick for ya wishlist
Get bent, you'll get a pinch in the bidness
She make 'em all geek when they view that
I told you, she got a backpack
But you already knew that
(She got a backpack!)
And a lunch pail too
Cheatin' when I'm sitting next to you
(She got a backpack)
And I got a ruler for her too
Now I'm bout to take her back to school
(She got a backpack!)
And a lunch pail too
And milk could do her body good too
(She got a backpack)
And I got a ruler for her too
Now I'm about to take her back to school
Like this!
Baby just shake ya
Your money maker
Looked her up, and down and said
"Hmm, I'll take her"
Break out my wallet, pay for that whatchamacallit
I knew she had a backpack from the front' fore I saw it
She's a stallion, got them boys hollerin'
Ballers, all of us, hope her and them girls come on and follow us
Them 816 Boyz, brand new Rat Pack
Lookin' for them girls
Packin' them backpacks
(She got a backpack!)
And a lunch pail too
Cheatin' when I'm sitting next to you
(She got a backpack)
And I got a ruler for her too
And I'm bout to take her back to school
(She got a backpack!)
And a lunch pail too
And milk could do her body good too
(She got a backpack)
And I got a ruler for her too
And I'm about to take her back to school
Like this!
