You sort-of have to hum the song while reading, and it's more entertaining if you can imagine Light singing.
GET'CHA HEAD IN THE GAME (Light)
Find the names of each one
And then write
Watch out for police
And keep a grip on the world
Gotta write the name, be smart
And built an utopia
But keep an eye out
For this detective "L"
…
Just keep ya head in the game
Just keep ya head in the game
…
But keep an eye out
For this detective "L"
Just keep ya head in the game
…
U gotta
Get'cha get'cha head in the game (repeat 6x)
…
Let's make sure
That I get the plan right
'Cause when I get it
Then the crime rate will drop
They call me Kira
Gotta think and deceive
Lind L. Taylor
40 seconds, your dead
…
Wait a minute
He died but he's alive
Wait a minute
Did "L" just trick me
Wait a minute
Get my head in the game
Wait a minute
Wait a minute
…
CHORUS
…
How did he know where I was
My head's in the game
But my dad disagrees
He's on the Kira-case
