Hi PH I'm m1chie, building solo from Japan.
Last March I shipped a tiny app called Song Bottle. It does one thing: you send one song you love, and a stranger somewhere sends one back. No login. No feed. No follower counts. A song for a song.
I assumed a few friends would play with it for two weeks and then forget. Instead the launch post got 90K likes, Japanese tech press picked it up, and the bottles kept flowing. iOS and Android followed.
Today, about 95% of users are in Japan. Which is wonderful and also exactly why I'm here.
Hey PH ๐ m1chie here, solo maker from Japan.
Song Bottle does one thing: you throw one song you love into the ocean, and a stranger somewhere throws one back. No login, no feed, no algorithm.
I shipped a tiny web version last March thinking a few friends would play with it for two weeks. Instead the launch post hit 90K likes overnight, Japanese tech press picked it up, and the bottles kept flowing. iOS and Android followed.
Today about 95% of users are in Japan โ which is wonderful, and also exactly why I'm here. The whole product is about hearing what a stranger somewhere would pick for you, but right now almost every "stranger" inside the app is Japanese too. I want to know what's playing in someone's headphones in Sรฃo Paulo, Lagos, Berlin, or Mexico City right now.
๐ถ Throwing my launch-day bottle.
"Bibibibi feat. SEKAI" by Frog96. Japanese internet music with a synthetic vocal (a software called SEKAI, modeled after a virtual singer).
No deep reason for picking this one. It's just been on heavy rotation for me lately and I want one stranger out there to hear it.
Stick with it past the first 30 seconds โ the second half is where it lands.
