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.
Song Bottle is a new way to discover music through people.
Send a song you love, add a mood tag or short message, and receive a song from someone else somewhere in the world.
No accounts. No algorithmic feed.
Just music shared by people.
