spotify: Authenticate API requests

[dtvu]

Problem

I was playing around with the Spotify plugin and I noticed that none of my tracks matched a Spotify ID. I wondered if this was potentially related to Spotify removing unauthenticated calls to the web API.

Setup

• OS: Ubuntu 16.04
• Python version: Python 3.5.2
• beets version: 1.4.5
• Turning off plugins made problem go away (yes/no): no

Hmm; interesting. Could you perhaps include some verbose output?

Thanks! Just seeing the setup output is useful in itself, but what would be really helpful is a verbose log from a situation where the problem actually came up. That might include messages that show failed requests to the Spotify API, for example.

Can do!

Looks like it is related to the removal of unauthorised calls, as visiting one of those URLs gives this response;

{
  "error": {
    "status": 401,
    "message": "No token provided"
  }
}

[sampsyo]

Thanks for investigating, @jackwilsdon! That does indeed look like the explanation. It looks like this plugin will need to authenticate its API requests.

Same here. I have created an app here - https://developer.spotify.com/my-applications/#!/applications so just needs a config setting to make it work!
