There's music in the treetops

And there's music in the vale

And all around the music fills the sky

There's music by the river

And there's music in the grass

And the music makes your heart soar in reply

When you find you've got the music

You've got to look inside and find

Find you've got the music

The music deep inside you

Find you've got the music

'Cause when you look inside, you'll see it

Find you've got the music

You're gonna find it, gonna find

You've got the music

Got the music, got the music

Got the music in you!

The Wonder Tones had just finished performing at Canterlot High, Fluttershy sang along as well, her friends cheered and clapped for her.

Rainbow: WOO-HOO!!!! YEAH!!! Way to go, Fluttershy!!!

Rainbow Dash ran onto the stage and hugged Fluttershy tightly.

Fluttershy: Uh, thanks, Dashie. It's still a work in progress.

Rainbow: Are you kidding? That was incredible!!!

Rarity: Ahem, there's someone else here waiting for a compliment!

Rainbow: Uh, you were great too, Rares. Except it could be 20% cooler.

All: RAINBOW DASH!!!!

Rainbow: ...What?

Pinkie: Whoa! I've never heard you sing, Fluttershy!

Twilight: You must have a gift.

Fluttershy: You think so?

Pinkie: We know so!!!

Rarity: I insisted that she should sing with us just this once. She has a golden voice.

Fluttershy: Um, thank you, Rarity.

Since this moment, Fluttershy's gotten used to singing in public, but for now, she's only singing to her friends.
