It was the song playing when Neno and Trinity fight the guards of the govt building when they went to save Morpheus.
Do you mean the infamous "lobby scene?" (which incidentally, was shot in one take because they didn't have the budget to redo all the simulated bullets). I think the song in the lobby was "Spybreak! (Short One)" by the Propellerheads. Also on the same disc, track 2, I think.
