Halo music on High Ground

This is an Easter Egg for the map High Ground that appeared in the Halo 3 Beta and Halo 3, that was changed slightly in the Halo 3 version.

How to
To hear the music, all you need to do is wait for a while in the computer room. The radio below the larger computer will eventually stop making static and morse code and will play either the Halo: Combat Evolved song Under Cover of Night, or random Halo songs (Halo 1, 2, or 3). You can tell it is about to play a song when it sounds like an FM radio just barely out of tune from a local station. Note, in Forge mode you can pick up the radio and place it in a different location, and it will still play music.
