Songs are hidden all over the real world

Travellers leave the song they were listening to at the exact place they were standing. Walk close enough and it appears.

Free. And it stays free.

How-it-works.txt
01

See what others left

Not a playlist — a memory, pinned where it happened, on the ring closest to its true distance.

02

Leave your own

Say something with it, or stay anonymous. It lands on other maps about an hour later.

03

Keep the ones that stay

They go in your backpack, with the place and the person you got them from.

Pick-a-face.exe

Fifty-eight drawn faces to choose from. It is an illustration, never a photograph — and you can leave a song without showing any of them.

Real screens, real pixels
Where-you-are
The app's top bar: the backpack button, the street you are on, and your avatar

The street you are standing on, and the face you chose. Tap the backpack to see what you are carrying.

Songs-nearby
Song markers sitting on the radar rings, each a disc with the artist and title under it

Each disc sits on the ring closest to its true distance, in its true direction. You walk towards it.

What-they-left
An open song card: cover, artist, who left it, the place, and the line they wrote with it

Who left it, where, and the line they wrote with it. The cover opens the track in Spotify.

Three-buttons
The whole navigation: home, leave a song, and the nearby list

That is the entire navigation. Home, leave a song, and the list of what is around you.

No feed, no followers, no algorithm. The only score the app keeps is how many countries you left a song in.

About-me.txt
Léo MullerSolo developer and designer

I design products, and this one is mine end to end — the pixel art, the app, the rules that keep it anonymous, and this page.

It came from something I noticed travelling: a place can get stuck to a song you would never choose. Making an app has started to feel too serious, and this one has none of that.

Not a travel playlist. The exact place someone was standing when a song became a memory.

Buy me a coffee

The app is free and it stays free. Nothing at all behind this — not a badge, not an extra, not a thank-you screen. There is no way to pay from inside the app, and nothing in it links here.

Go outside

The next song is wherever you are standing. Free, and it stays free.
