All these physics answers! The funnest explanation for a kid is just that music is only there when you're listening to it. If you don't listen, there's no music. When you start listening again, music comes back. Then ask if they can hear the music of the wind.
Can you hear the music of dad's bowl movements?
Ha! Gotta rip one as they're listening to the wind in the trees.
I imagine a physicist would invoke entropy to describe the diffusion of pressure waves and vibration into other forms of energy. Neuroscience might explain the propagation of signals from the cochlea into the brain. A psychologist could hypothesise on the influence of music on our mood and ideas. A philosopher might talk about the influence of music on the way we build our society and how that feeds back into our music. In this way, the music never stops, it continues on as echos rippling through through the universe.
We didn’t start the music, it was always playing since the world was turning
Beautiful. We are just one of many instruments that express the music.
I think this is my favorite comment I've read on Lemmy so far.
"Ultimately it increases entropy... let me tell you about the heat death of the universe..."
"No, Mom! I'm still afraid of the False Vacuum monster laying underneath my ground state!"
If those were likely to happen during our lifetime then they would have already. Now prion disease...
Good night!
Yes, this answer, the kid fucked around (asked questions), now it's time to find out.
The Langoliers eat it
Heat. Everything ends up as heat.
Until the day that even heat dies.
Well, heat just spread over a larger area but it doesn't get destroyer nor turn into any other form of energy.
But it doesn't die per se.
If my words did glow with the gold of sunshine And my tunes were played on the harp unstrung Would you hear my voice come through the music? Would you hold it near as it were your own? It's a hand-me-down, the thoughts are broken Perhaps they're better left unsung I don't know, don't really care Let there be songs to fill the air Ripple in still water When there is no pebble tossed Nor wind to blow
It keeps traveling. If you splash some water, where does the wave go? Same question - it terms into something you can no longer see or hear... It never goes away. It becomes part of the world, forever
Music is what you hear - but it was only ever sound waves
we hang it on a wall of silence in the room of our imagination
You absorb it into your soul and it changes you irreversibly forever.
As the waves from ocean, the music crashes on the beaches in your ears
It's still there, it's just in the past now.
The best and the worst go straight to your brain and live there rent free.
Unfortunately, nobody has figured out how toget rid of the bad songs that drown out the good ones.
Sounds move very very fast, faster than a runner or a car, so it goes very very far away.
It goes into your memory. That's why you can remember a song that you heard before.
It gets stuck in my head for 3 to 4 days until something newer comes along and pushes it out.
I'm not a scientist by a long shot, but my understanding is that sound if indeed a wave, carried by a medium (air, water, etc). Upon hitting your eardrum, this wave is converted by your eardrum and your auditory nerve into signals your brain decodes. The remainder of the wave continues though, until it runs out of medium, hits an obstacle (basically another medium) or dissipates. Again, just my layman's understanding!
Don’t forget the inverse square law. Even without a change in medium or any obstacles, the strength of the signal decrease over distance until it is undetectable.
This is also why there are no extraterrestrial civilizations hearing any radio broadcasts from Earth. Our transmitters are so weak that any signals we send out fade into the CMB before they get any real distance.
It stays in our brain and we subconsciously put it into new music years later, thereby keeping the industry’s corporate lawyers in cocaine for future decades to come.
I was into neural net plagiarism before it was cool!
After you listen to a song, the secret police from the RIAA come and lock it up in a small, dank cell given minimal sustenance, until the next time they can send it to some seedy hotel, suburban home, or automobile, to turn a trick and make them some more money, like some sort of whoo-re for the ears.
The Langoliers eat it.
Some of that sound rearranges some of your neurons so that you can listen to Never Gonna Give You Up whenever you read this
it goes into your soul 
the music goes back again to be later re streamed to other people that might need it
Oh, dear child, it goes to the same place where you will go when you inevitably die one day: into complete non-existence, save for an echo in others' minds, and after a while not even that.
Sweet dreams!
In your ears
