To piggy back off your comment, for people with a disposition for electronic music I've curated a playlist over the past 6 or 7 years of largely lyricless progressive house, techno, and electronica that helps me enter a "flow state" when I'm working. I'll share below. It's nearing 300hrs long but I add to and prune it almost everyday. I personally find classical music to be too distracting/engrossing, while the aforementioned genres I find soothing to work to.
