(Also not Hero of Equestria related, I'm still struggling to come up with something for Y/N. >.<)

[There should be a GIF or video here. Update the app now to see it.]

A small blue light is floating in a zone where there's nothing but darkness. When the light touches the floor and it shines brightly before being replaced by a blue earth pony that's wearing a blue tie, a black earpiece, but the most noticeable trait is her long cyan twin tails.

The pony opens her light blue eyes and starts singing .

🎶Now I don't want to let myself forget these unshakable feelings🎶

🎶I break the templates, the mold, the norm, the layout in my heart🎶

She starts spinning and dancing as glowing musical notes start surrounding her in a rainbow colored aura.

🎶I hum a simple phrase, the music plays, I feel it inside of me🎶

🎶Those words I held with me🎶

🎶To set them free I raise my voice and sing to the sky🎶

The musical notes start spinning at incredible speeds, blasting off like fireworks before making a colorful explosion, lighting up the dark space, filling it with bright colors.

🎶CAUSE EVERYTHING I KNOW I WANT TO REACH YOU🎶

🎶AND ALL THE THINGS I KNOW I WANT TO TEACH YOU🎶

🎶THE POINTS ACROSS THE WORLD ALL COME TOGETHER🎶

🎶TO FORM AN ENDLESS LINE ACROSS FOREVER🎶

A lot of colorful magical spheres started appearing out of nowhere and surrounded the pony. Each sphere had a different symbol inside of it, a star, an apple, a diamond, a balloon, a butterfly, a lightning bolt, all types of different cutie marks.

🎶'CAUSE ALL THESE DIFFERENT WORLDS I WANT TO BRING YOU🎶

🎶AND ALL THE DIFFERENT SONGS I WANT TO SING YOU🎶

🎶THE LINE COMING TOGETHER FORMS A CIRCLE🎶

🎶NO MATTER WHO YOU ARE OR WHERE🎶

🎶CONNECT AND TELL YOUR WORLD🎶

Then multiple colored lines started connecting each and every single one of the cutie marks as they all start shining brightly.

Then the Earth Pony smiles and sees a small white orb floating towards her.

🎶A bright and gentle light, a brilliant white, I'm somehow reminded🎶

🎶Your voice comes back to me, into my hand and rests within my palm🎶

She extends her hoof and the orb lands on it as she holds it gently.

🎶And as I hold it there, I'm now aware, I'm humming a melody🎶

🎶And as it comes to me🎶

🎶To set it free I'll raise my voice and sing to the sky🎶

She hymns and the orb starts glowing blue as a musical note symbol appears in it before she blows it away, the orb floated in the air before exploding in tiny glowing particles.

🎶CAUSE EVERYTHING I KNOW I WANT TO REACH YOU🎶

🎶AND ALL THE THINGS I KNOW I WANT TO TEACH YOU🎶

🎶I TIE THEM TO THE LINE AND SEND THEM OFF TO🎶

🎶THE TANGLED WEB OF LOOPS IT'S TURNING INTO🎶

The blue floating particles started glowing and surrounding and surrounding the pony. The louder she sang, the brighter the particles glowed.

🎶'CAUSE ALL THESE DIFFERENT WORLDS I WANT TO BRING YOU🎶

🎶AND ALL THE DIFFERENT SONGS I WANT TO SING YOU🎶

🎶THE LINE FORMS DIFFERENT SHAPES AROUND THE CIRCLE🎶

🎶NO MATTER WHO YOU ARE OR WHERE🎶

🎶CONNECT AND TELL YOUR WORLD🎶

🎶AH🎶

Each particle flew away towards each cutie mark, touching them and shining brightly for a brief second.
The pony then walks past a virtual hall where she could see multiple screens showing ponies on their daily lives with bright glowing auras and virtual music notes surrounding them.

🎶I'm dancing through a maze of unchanging days🎶

🎶I sing my tunes along the way🎶

She then notices one pony who has no musical aura, looks at him with caring eyes and puts a hoof on the screen before going through it. She suddenly appears next to him like some sort of ghost and offers her hoof to him which starts glowing a light cyan color.

🎶And I start to think they're gifts to us🎶

🎶Each and every single brand new day🎶

The unicorn looks at her confused before eventually taking her offer and she helps him getting back up. She then puts her hoof on his chest and starts humming, making him feel a strange feeling inside. Eventually he starts humming with her and they both start glowing in a rainbow colored aura as a musical orb gets formed  and slowly starts descending towards them.

🎶The sound is growing more, I'm shaken to my core🎶

🎶Believing it's what I'm here for🎶

🎶So please tell me more🎶

They both hold the orb and look at it in awe. She then signals the unicorn to raise his hooves and let the orb go in the air. As the orb slowly floats, it then suddenly explodes into tiny rainbow colored particles that start raining on top of them. For a brief second, the unicorn's eyes glow rainbow before going back to their original color. He then starts tearing up with a smile on his face.

🎶And share with me🎶

🎶To Tell Your World🎶

The scene now changes to the blue pony on a stage singing and dancing to a massive crowd. Many glowing orbs with music notes in them are floating on top of her as a rainbow aura starts coming from the pony.

🎶CAUSE EVERYTHING I KNOW I WANT TO REACH YOU🎶

🎶AND ALL THE THINGS I KNOW I WANT TO TEACH YOU🎶

🎶THE EVER-GROWING CIRCLE GAINS DIMENSION🎶

🎶TO A COSMIC SPHERE OF INFORMATION🎶

As she sings, the rainbow aura shoots towards the orbs, connecting every single one of them like a web before exploding in the air, creating a beautiful spectacle of shining lights.

🎶'CAUSE ALL THESE DIFFERENT WORLDS I WANT TO BRING YOU🎶

🎶AND ALL THE DIFFERENT SONGS I WANT TO SING YOU🎶

🎶AND ON THAT SPHERE WE LIVE OUR LIVES TOGETHER🎶

🎶NO MATTER WHO YOU ARE OR WHERE🎶

🎶CONNECT AND TELL YOUR WORLD🎶

🎶AH🎶

As she finishes her singing, she looks at all the ponies in the stage cheering in joy. As she's waving and thanking everypony, she then notices the same unicorn she encountered before amongst the crowd cheering for her.

She can't help but wave at the crowd, thanking them with a smile on her face by the sight of seeing so many ponies from all around the world having a good time, all of them being united by music.
