I probably listen to this album from start to finish at least twice a week. Depending on my mood, I can listen to this on a loop five or six times before I get bored with it. Soultrane by John Coltrane is the quintessential writing music and perfect background music. If this was the only album I had, I wouldn't be too bummed out.
I created a jazzy writing playlist over at YouTube. Check it out here before the YT Police yanks them down.
