Music
The way you feel when you're listening to your favorite song or favorite band.
The way some songs make you want to sing for the whole world to hear, even if you don't usually like to.
The way a song gets stuck in your head and leaves you thinking about it all day.
The way the birds chirp on a sunlight-filled day, or the way the crickets chirp on an ebony night lit by the luminous moon.
The way it feels when someone listens to that song that you reccommended to them, and the way it feels when they say they like it, too.
The way a song fills you to the brim with boiling excitement and ecstacy, or the way a song pulls tenderly at your heartstrings.
The way you feel when you hear your favorite show or video game's themesong or soundtrack.
The way you feel when you listen to your favorite singer's unique and lovely voice weave to you tales of anything and everything.
The way you feel when that instrument you've been working so hard to master makes a pleasant sound, or the way that song you've been practicing finally falls together.
The way you feel listening to good music.
