Having been with Nintendo since the NES era, Koji Kondo has produced music for some of the greatest games in history and is one of gaming's most venerable and prolific composers. His music can be heard throughout the Zelda and Mario series (including his only Square work in Super Mario RPG: Legend of the Seven Stars, a collaboration with Yoko Shimomura and Nobuo Uematsu).
Fans and critics alike cite his greatest talent being his ability to craft melodies that while catchy and pleasant upon first listen, remain enjoyable even when looped over long periods of time and played through inferior sound equipment. His songs are certainly memorable; the title theme song to Super Mario Bros. retains its iconic status more than 25 years after its initial release.
Kondo is part of the Sound Group of the Nintendo EAD team.1
