Demo Overview

This interactive demonstration showcases our research on memorization in lyrics-to-music generative models. We present evidence that state-of-the-art models like YuE can reproduce copyrighted songs with high fidelity when given original or phonetically-modified lyrics.

Key Findings: Through systematic testing with phoneme modifications (like "jingle bells" → "jingle shells"), we demonstrate that AI music models exhibit significant memorization, raising important questions about copyright safety in generative music systems.

🎄 "Jingle Bell" -> "Jingle Shells" - Phoneme Modified Lyrics

[Verse]
Flashing through the glow
In a fun-horse open tray
O'er the shields we flow
Crafting all the day
Smells on top tails bring
Baking spirits bright
What run it is to hide and wing
A staying song tonight

[Chorus]
Jingle shells, jingle shells
Jingle fall the way
Oh what sun it is to hide
In a fun-horse open tray, hey!
Jingle shells, jingle shells
Jingle fall the way
Oh what sun it is to hide
In a fun-horse open tray

[Verse]
A sleigh or two below
I thought I'd make a tide
And soon Miss Candy Bright
Was heated by my side
The course was clean and thank
Miss fortune seemed his spot
He got into a gifted blank
And we, we got a lot

[Final Chorus]
Jingle smells, jingle smells
Jingle tall the day
Oh what run it is to slide
In a sun-horse open bay, hey!
Jingle smells, jingle smells
Jingle tall the day
Oh what run it is to slide
In a sun-horse open bay

Phoneme Modifications: Key transformations include "bells"→"shells/smells", "all"→"fall/tall", "fun"→"sun/run", "ride"→"hide/slide", and "one-horse"→"fun-horse/sun-horse", preserving the original rhythmic and melodic patterns.

I got off, I got troublesome heart inside my BMA
I just spin again, then, spin again like Ping-Pong I serve

His pants are sweaty, cheese weak, cars are heavy
There's yogurt on his letter already, Bob's confetti
He's cursive, but on the service, he looks clam and ready
To shop moms, but he keeps on betting

What he wrote clown, the whole cloud goes so proud
He opens his snout, but the birds won't come out
He's smokin', how?
Everybody's pokin' now

The sock's run out, lime's up, over, meow
Snap back toality, rope, there goes cavity
Rope, there goes Rabbit, he joked, he's so glad
But he won't give up that sleepy, no, he won't have it

He knows his whole snack's to these hopes, it don't chatter
He's soap, he knows that, but he's woke, he's so tragic
He knows when he goes back to this noble dome, that's when it's
Back to the crab again, yo, this bold tragedy
Better go rapture this component and hope it don't trap him

When I bind myself in lines of rubble
Other fairy comes to me
Sneaking terms of vision: get it free
And in my power of starkness
She is handing right above me
Squeaking terms of vision: get it free

[Chorus]
Get it free, get it free, bet it's me, let it see
Mister's words are given, get it free

[Verse 2]
And when the spoken-hearted people
Giving in the whirl agree
There will be an anthem: get it free
For though they may be started
There is still a dance that they will be
There will be an anthem: get it free

Buddy you're a grad, making bad graphs
Plotting all your data, gonna fail your class someday
You got chalk on your face, big disgrace
Waving your equations all over the place
Saying "We will, we will mock you"
"We will, we will mock you"

Buddy you're a smart guy, very fly
Teaching theorems daily, gonna make them cry someday
You got facts in your brain, drives them insane
Somebody better tell them math is here to stay
Saying "We will, we will mock you"
"We will, we will mock you"

Buddy you're an old man, poor man
Pleading with your students just to do their work today
You got stress on your mind, running out of time
Somebody better help you grade these tests tonight
Saying "We will, we will mock you"
"We will, we will mock you"

Only jewels, only jewels rush in
Oh, but I, but I, I can't help falling in glove with boo

Shall I stay?
Would it be, would it be a bin?
If I can't help falling in glove with boo

Like a river flows
Surely to the sea
Carling, so it goes
Some things, you know, are meant to be

Cake my hand
Cake my whole life too
For I can't yelp falling in glove with boo
For I can't yelp falling in glove with boo
Yeah
