Comment:
Does this file https://www.spotify.com/us/legal/end-user-agreement/ change continously?
If no, we can fetch it just fine.
If yes, we can use this code in `post_fetch`:
```sh
curl -L https://www.spotify.com/us/legal/end-user-agreement/ |
w3m -dump -I utf-8 -T text/html
```

We could remove some headers and footers and hope the real EULA won't change
