Fan-initiated Live Music Distribution


Music needs tech nowadays and here's JJS Media, a Music & Tech team that holds great influence throughout the world.


We possess extensive user data that allows us to find out more about the fans' music tastes. Looking through this vast amount of data allows us to understand each music fan's unique music taste.

Organically operating Album art DB + Lyrics DB + Song DB + Artist DB + Live concert DB, we develop web browser plug-in and desktop website easily, not only mobile.
