"Common Fight" plays when a suitably epic moment is happening (such as escaping the Kalinatek building, the showdown with Grinko and his mooks in the abattoir, and the shootout in the Presidential library). Also doubles as an Autobots, Rock Out! song. Unless you were playing the PS2 or Gamecube versions of the game, in which case this awesome track was only used once during the escape from Kalinatek.
The whole score by Jack Wall is much more atmospheric than that of the first game. Among the tracks that stand out, "Jerusalem" is the perfect musical atmosphere to infiltrate a Middle Eastern city by night.
Amon Tobin's whole score is made of breakbeat, IDM and especially Drum and Bass. It captures the game's atmosphere so well that it seems astonishing that they didn't keep him on retainer for the rest of the series. For example, "Battery" is really good at setting in the mood.
The 3DS port of Chaos Theory received a mixed reception, but almost everyone agrees that its theme song "Breaking Protocol", once again by Amon Tobin, kicks ass.
"Got Yourself Locked Up" on the original soundtrack not only fits during tense moments in stealth and action, but it's very fitting to the series as a whole.
