I went through a period of listening to zelda soundtracks + rain/storm sounds for hours every day at work. It was very calming and there wasn't much to focus on, which let me focus on my work. Video game soundtracks in general can be excellent programming music because they can be looped infinitely and are designed to be in the background of some other task.
I agree! I often listen to music from World of warcraft when coding. I get in a similar grinding mindset I had when I played back in the days. Helps me focus a lot!
Zelda & Chill by GameChops is a good one. GameChops has a lot of other lo-fi video game soundtrack covers that are great for programming, in my experience
My goto right now is https://www.twitch.tv/sgqfmfunk, which streams video game OSTs from the 80's and 90's -- mostly relatively obscure games, including a lot of music from consoles/home computers that used Yamaha's FM chips.
Anyway, I listed to https://rainwave.cc all the time. Video game music with 5 different channels (no ads!). It's great (although there are a few songs with vocals, which I don't like. Not on the chiptune channel though ;)).
