Mr J is the Swedish guy that make cute electronic music in order to cheer people up with his happy, and some times video game inspired melodies.
He started making music in 2003, with Commodore 64 tunes (so called SID tunes), but soon went on doing music with the ModPlug Tracker (a tracker that supports a various kind of module formats, including MOD, XM, IT etc). In the spring 2004 a Mr J song was played on Swedish national radio, SR P3. Since then has polished his way to make music and developed his own sound.
