As someone with ADHD this is the only way I can get coding done. I put on usually 3 to 4 noises, at least one of them musical, and set them to a standard slider animation. Duduk Song and the Japanese Oase are two particular favourites, and the vocal generators are all pretty amazing. Oh! And the tuned cave droplets.

I find also it doesn't tend to become its own distraction. Once I find a group of sounds, the only way to experience them is to put them in the background and let them go while I do other things, so it actually helps me get started.

Donating was a very good use of a few dollars.
