Ooh!
As @jgonzalez already said it depends on what sort of work I’m doing and what kind of mood I am in.
When I’m relaxed and just trying to get something done, I will usually listen to relaxed music like
The FatRat
or Retro Synthwave like
Dance with the Dead or Scandroid
When I’m more energized and really trying to make some serious progress, I will listen to heavy metal like
the DOOM 2016 OST (which is also great for tuning out the outside world btw, you get completely lost in those)
or my favourite metal band Fear Factory (Demanufacture)
And a final pro tip when working on a large project, where you want epic music that makes your heart do some serious pumping: Dark Souls 3 Main Menu OST
I have this on my phone too and it’s so amazing, I love it! 😀
