just as i got diplomacy and heard the awesome piece of music in the main menu,  it reminded me of the BETA of sins vanilla (im sure i've heard it before there)

and made me look for the audio file,

in search of that audio file in the sound folder i've also found some other audio effects and very nice themes that i've never heard before in-game, an example being the file "tec opening.ogg" or "tec 4.ogg"

i spend many hours/week on Sins, TEC being my fav. race  but i have never heard the above named themes


my question is,  are these (intentionally) left out of the game?
