You hear a white noise thrum before the three piano notes. They linger in your mind for a space, and then the next three piano notes resolve the phrase, that white noise thrum underlying everything. All of this will recur several times while you sip your coffee, strong and black, and you hear a bass note repeat with increasing frequency: it's pressing you, until a new pitch pushes the white noise upward into the second track and its expansive layers over the beat. Your mind quickens and your fingers come alive, yearning to type.
At least, that's how it works for me when I brew some coffee and put on Trent Reznor and Atticus Ross's soundtrack to The Social Network. Other beverages are acceptable substitutes, I suppose, but there's a purity to drinking one's coffee black, particularly if you grind your own beans.
