Soundtracks for the first two games were produced by Iku Mizutani, Shigehiro Takenouchi, and Motoaki Furukawa. For Metal Gear Solid, Kojima wanted "a full orchestra right next to the player"; a system which made modifications such as tempo and texture to the currently playing track, instead of switching to another pre-recorded track. Although these features could not be achieved at that time, they were implemented in Metal Gear Solid 2: Sons of Liberty.[136] Hideo Kojima chose Harry Gregson-Williams, a Hollywood film composer from Hans Zimmer's studio, as the composer for Metal Gear Solid 2 was highly publicized in the run-up to the game's release.[137] Gregson-Williams would reprise his role in Metal Gear Solid 3 and Metal Gear Solid 4.[138] Starting with Metal Gear Solid, theme songs have been provided by popular artists such as Rika Muranaka.[139] Several soundtracks based on the games have also been published.
