The Reloaded Soundtrack is really good, but I prefer disc 2 which features all the background music in the movie. It really kicks ass. *Potential Spoilers Ahead*
Main Title: Says it all. The background music (BGM) when the movie starts
Trinity Dream: BGM at the part where Trinity falls off the building.
Tea House: BGM when Neo was fighting the Oracle's assistant in the tea house. A nice throwback to the old kung fu movies.
Chateau: My bro tells me the title means "castle". Anyway, it was played when Neo fought the French guy's goons in his home, which was a castle.
Mona Lisa Overdrive: Clocking in at 10 mins, this was played during the freeway free-for-all scene. Very nice and panicky.
Burly Brawl: My favourite. The scene where Neo plays baseball with the Agent Smiths, only that the Smiths were the balls. Best track of the CD.
Matrix Reloaded Suite: This is just a mix of all the BGMs, wasn't played during the movie.

Listening to Burly Brawl makes me imagine that scene again and again...
