Work music

I absolutely can not listen to music with lyrics when I'm working; really messes me up with the whole reading and writing thing. So I'm always on the lookout for new ambient tunes. These are my top five writing albums.

• Tycho's Dive
• Pilotpriest's Original Motion Picture Soundtrack (the new Darknet is pretty great too)
• Trent Reznor and Atticus Ross' soundtrack for The Girl with the Dragon Tattoo
• Com Truise's Galactic Melt
• Jim Guthrie's Sword & Sworcery soundtrack

What do you guys listen to while you work?
