Many people on Youtube comment the same things on the GK2 trailer:
"Epic song!"

For those of you who did comment that, thinking about commenting that, or aren't commenting it but agreeing to it, I have the soundtrack of the theme that plays before the Logic Chess scene and after the Logic Chess scene! They may possibly be the new cornered themes!

NOTE: They may not be 100% Accurate (They are 99% or more accurate). I used Audacity for these songs!
If you want, you can post your opinion on these two songs and be the new Judge!
