High School Musical 3 Soundtrack!

I got a little more information about the future Junk Yard song featuring Chad and Troy for High School Musical 3! Apparently they stomp around on cars, sing and bang trash cans!
Also, i am recently told and it is rumored that the cast of hsm is now working on recording the new hsm3 songs. I find this hard to believe because 3 of the main stars are making movies. But maybe they are recording somehow and they don't want anything to leak out!
And, i know that the recently rumored tracklisting is definitely not real so those songs like "Miss is Coming To Here", "Mixin My Turn" or "Hollywood In School" are not real.
