music while you work

What do you listen to while you work?

Two Steps from Hell if i want to feel uplifted, motivated, excited.

the trent reznor/atticus ross movie soundtracks (The Social Network, Girl with Dragon Tattoo, Soul) if i want to think.

masakatsu takagi is good too, the epitome of iyashikei soundtrack.

but mostly, and especially when doing Serious Work, i need silence.
