I suppose I should link my own Music For Coding To playlist here, for anyone who might be interested. I've tried to refine it over the last 7 years, removing tracks with vocals & anything that throws me out of the flow state:

It's intended to be played on shuffle, but I've started my workday with Ulrich Strauss' "I Take Comfort In Your Ignorance" so many times that just hearing the track can trigger me into a working mode.

As for recommendations, I like the album "Aura" by The Alpha Conspiracy. Trackers and demosceners might know him better as Necros from Five Musicians, and he wrote some of the soundtracks used in the Unreal games. His real name is Andrew Sega.
