I'm either retarded or a genious-The dev's plan for, or scratxhed orbital platforms.

Captain Obvious to the rescue! The music couldn't be easier to find, considering it's in plain invividual-file MP3 format in a folder clearly marked "music"... I wanted to listen to one track some day a while ago, and I just popped open the Planetside folder and it was right there staring me in the face.

The reason Orbital Platforms were taken out is because they added nothing to the game. All they did was create an unnecessary and quite possibly annoying delay between getting in the HART and dropping down to your chosen location. Therefore, they are deactivated until the devs can think of an actual use for them. Several have already been suggested on the official forums, but there is no sign of movement in this direction.

Also, the Orbital Platform music track is actually used in the game. It plays when you're inside the HART building. If you don't believe me, turn up the music to 100%, hang around outside in Sanc for a minute, then walk into the HART building and listen to it change (give it a bit of time to cross-fade the tracks). Note that standing very close to the building, even if you're not technically inside it, can cause the music to trigger.
