I clicked into one of the featured seeds, then clicked to open the seed in colab. https://colab.research.google.com/notebooks/magenta/music_va...

Then I click the first little play button for "Setup Environment" then it gives me that error. I'm on chrome 67.0.3396.99 on OSX, and I do in fact have third party cookies disabled (for the usual privacy reasons).

Specifically it is `NotSupportedError: Failed to register a ServiceWorker: The user denied permission to use Service Worker.` which is probably due to the privacy settings?

Unfortunately I believe Colab needs this to work :/
