Let's see how many we can come up with.
Pillar of Autumn: The Megg - for an employee's girlfriend. Very tricky to get to.
AotCR: Johnson's Speech - You have to slide down the wall from the first bridge. This isn't heard in the game unless you do this trick.
Siege of Madrigal - Fly high up outside of the control room and land on the right side of the 3rd structure around the light beams. Wait a few seconds to hear the music.
343 Guilty Spark: Dead Marines in start area - You have to go down the lift, then come back up immediately. Dead Marines are scattered from the structure entrance all the way back to the crashed Pelican. Some Grunts stuck in a tall tree and the Spirit too.
The Maw: Rex(not in CE:A!) - Land just to the left during the big jump and head into the left corridor.
