To Sleep

To Sleep is a track included in the Halo: Combat Evolved Anniversary: Original Soundtrack. It is a remake of Perchance to Dream from the Halo: Original Soundtrack. Like Perchance to Dream, its name comes from the "To be, or not to be" soliloquy in William Shakespeare's Hamlet, the words "To sleep" directly preceding "Perchance to dream". It runs for 1:04.
