A friend of mine listens to classic jazz music. Very soothing and relaxing while working.
As for me, I listen to light rock music, mostly 80s-90s music. Keeps me thinking about the good old days, nostalgia. It also allows me to concentrate on my tasks.
I love questions like these, where anyone can answer and it's a bit fun.
I don't listen to anything, but that's mostly because I'm worried I'm going to miss a notification sound or something haha. If I'm less anxious about it, then I'll put on some indie punk or a relaxing playlist from Spotify. If it's a really light day, then I might even put on a show I've been meaning to watch in the background.
I usually listen to talk shows on NPR while I work. I find that the kind of music I listen to, when I do, needs to fit the emotional mood of the piece on which I am working. So if the piece is somber the music can’t be light and lively and vice versa.
