I always find HN's recommendations for focus/coding music fantastic and helps really expand my horizons of what's out there. I think it was HN that introduced me to Low-Fi Hip-hop as an example.
Recently I've been really listening to a lot of the new Underworld Drift music and Spoq (both on youtube) depending on my mood, though I tend to sort of steer towards old fashioned proto-IDM music like the classic Artificial Intelligence albums by Warp Records, and the Ambient works by Aphex Twin. The Black Dog by Spanners is sometimes incredible.
What are you listening to these days?
Otherwise, I've been on a Synthwave/chillwave kick, since it reminds me of my younger years (80's/90's... rose-tinted glasses and all that). The Midnight; Brian Eno; Tycho; Tangerine Dream; etc... or whatever comes up on Tidal and Spotify.
My favorite though is Spotify's "Synthwave from Space" playlist[3] from aofd3. Otherwise, hard rock/metal, classical, ambient/"concentration" style playlists, etc... anything really, depending on what I'm doing. Sometimes just a local terrestrial radio station is good enough.
