I'm a fan of ambient and instrumental hip hop for programming.
My personal favorites are pretty much anything by Nujabes (including the soundtracks for Samurai Champloo), Fat Jon, and DJ Okawari.
I also like some classic albums in the genre like Donuts by J Dilla, Dr. No's Oxperiment by Oh No, and Endtroducing by DJ Shadow.
I will sometimes go through essential charts I find to dive into new genres, and other times I'll pick a random artist and go through their entire discography start to finish.
I highly recommend doing that with Talk Talk, their transition from 80s pop to experimental is phenomenal.
Based on what you've already mentioned, there's a good chance you're familiar, but on the off chance you're not: "Funkungfusion" (or, really, anything off the Ninja Tune label) might be right up your alley.
same. combining the 10 volumes of Special Herbs makes a good 5 hour playlist too
