Bad Here Day
From Halopedia, the Halo wiki
Bad Here Day is the second track from the Halo Wars: Original Soundtrack.
This soundtrack, along with its alternate version, plays during Halo Wars's gameplay on any interior of Shield 0459-based campaign or Skirmish levels, though the alternate version only plays in the beginning of the levels. The standard version also plays randomly on any Harvest-based campaign or Skirmish levels.
The name of this soundtrack is a play on the common phrase "Bad Hair Day".
