all right, it took an extra evening for my (more-tech-knowing) gf to do some audio magic to give it nicer metadata and make the files smaller, but I finally got it uploaded, here it is: https://neonpixii.itch.io/cwkb-mp3. If you need me to change any of the wording on that page, let me know.
And if you do ever feel the desire in the future to instead host these files directly on your own itch page, please feel free to just do so (I do feel kinda awkward/sheepish hosting something I didn't make under my own itch username).
