You should try Brain.fm. I use it with my noise canceling headphones and the experience has been great so far.

I have a similar lightweight script I wrote [1] to generate white noise (actually brown noise) to concentrate when the office is busy.

There are a few other similar alternatives at the bottom of the readme, which I'll copy here for convenience:

- A Soft Murmur

- Brain.fm

- Coffitivity

- GitHub Audio

- Hipstersound

- Noisli

- Noizio

- SimplyNoise + SimplyRain

- Spotify playlists in the Focus section e.g., Ambient Chill, Deep Focus, or Music for Concentration

- Vicinity

- zenmix.io

http://somafm.com has some good instrumental channels, too. I also have a playlist of things I've curated from Magnatune over the years, there are some strong instrumental artists over there.
