Savestation Music (as named in the Metroid Prime internal files) is an ambient theme in both Metroid Prime and Metroid Prime 2: Echoes. It plays in nearly every Save Station in both games, and in Map Stations in the first Prime. However, this only applies to rooms with a Save Station where the room's sole purpose is to give the player a place to save, and not to larger rooms containing a Save Station (such as the Crater Entry Point or Sky Temple Energy Controller). The same goes for the Map Facility on the Frigate Orpheon in Prime. However, it does play in Transport A Access in the Great Temple, where the Save Station is a separate part of the room, accessible by a Morph Ball tunnel. In Prime, it does not play in the Orpheon Save Station upon her first visit, but it will play when she revisits it after the frigate crashes onto Tallon IV. The theme is primarily composed of constant "exhaust" from the Save Station, and a frequent synthesizer. It was replaced in Metroid Prime 3: Corruption by a variation of the Silence theme. The theme was composed by Kenji Yamamoto, and is one of the few themes from Prime to not be present on the Metroid Prime & Fusion Original Soundtracks.
