The beautiful song before "Meltdown" from the OST
So it was actually removed from the soundtrack, titled "Meltdown Precusor". It's the gorgeous song playing while Mike Wallace, Lowell Bergman, and Jeff all watch the defanged interview. This is all I could find. This guy's Wordpress page talk about what was omitted and other composers that contributed to the soundtrack.
But "Meltdown Precursor" can only be found in this form :(. https://soundcloud.com/fabiopirovano/meltdown-precursor-meltodown
