The Metroid Prime Credits not only plays during the staff credits in Metroid Prime, but looped differently in the menu as well. This also plays during the game credits. On the Metroid Prime & Fusion Original Soundtracks, the menu theme is titled Menu Select, and the credits theme is titled Ending Staff Roll. It was used in the E3 trailer for the sequel to Prime, Metroid Prime 2: Echoes. 
The credit theme, titled Metroid Prime - End Credits, appears as the penultimate track in GameSoundTracks: Original Videogames Music Tracks #1, a 2003 soundtrack offered by German gaming magazine Man!ac. Metroid Prime Credits is also included as a track on the Samus Archives Sound Selection CD that is bundled with the Special and Legacy Editions of Metroid: Samus Returns, where it is simply titled Metroid Prime.
