I just built this on my media player because when I've working I've found that this kind of music works best to keep me focused. Some elements of space rock and ambient with strong guitar seems to be the theme but I could be talking out of my ass. Regardless, I find this to be quite helpful when churning out words at my desk. Unintrusive but enough going on to keep my brain engaged. Any suggestions as to what I should add?

Pat Metheny - As Falls Wichita, So Falls Wichita Falls (just the title track)
Vietgrove - The Stellar Nursery
Ephemeral Sun - Harvest Aorta
The Future Kings of England - The Fate of Old Mother Orvis, The Viewing Point
