I like Mini Motorways in creative mode for this purpose. You design road systems to connect houses with businesses using limited resources. The music is very peaceful and the pastel colours are very pleasant on the eye. While the other modes are a bit more stressful, creative mode is like a simplified city builder.

And of course the perennial favourite, Stardew Valley.

I have music playing in my head most of the time, by default. Only if I’m doing something cognitively demanding does it pause or the ‘volume’ drop to 0 but keep going in the background

If anyone needs a more comprehensive explanation:

• This comic became a popular meme many years ago
• Those memes evolved to include overly simplified illustrations, like depicting the characters in each panel as lines like I Iı II I_
• That last panel simplified looks kind of like the letter L
• L in Roman numerals is 50
• Turning back into digits, you get 1 2 2 50
