Web Radio to Spotify

As a big fan of Classic Rock living in France, I am very frustrated by the lack of good classic rock radio we have. I spent four months in St Louis, MO, and I had the chance to listen to KSHE 95 every day, playing some of my favorite classic rock tunes. Unfortunately, I can't listen to this radio in France as they block it. Fortunately, their website shows the tune currently playing, as well as a few previous ones.

I decided to make myself an empty Spotify playlist, and automatically add in the KSHE tracks. I also wanted to be able to add songs from other similar Classic Rock radio. So I built a reusable architecture that enables to register different web scrapers to get the radio playing history and add that into my playlist.

So far, I am able to get the songs from these radios:

• KSHE95 (St Louis, MO)
• The Eagle 969 (Sacramento, CA)
• Q104.3 (New York, NY)
• 102.9 MGK (Philadelphia, PA)
• 95.5 KLOS (Los Angeles, CA)

Feel free to ping me if you want to help!

Installation

To make it work, here's what to do.

First, you'll need to setup your Spotify developer account, and register an app. Find how here. Once your app is created, you will have access to the following crendentials:

• client_id
• client_secret
• redirect_uri

Find you user_id (your spotify username) and add these 4 credentials in a file called .spotify-token.json. You have a template here: .spotify-token.json.dist. The app will need those to update tracks to your playlist.

Note: in this application, the redirect URI must be http://localhost:9999/auth/callback.

Once you're good, install the requirements in a virtual environment:

pip install virtualenv  # if you don't have it already
virtualenv venv
source venv/bin/activate
pip install -r requirements.txt

The app uses an sqlite database to store all the songs it has downloaded so far. You have to initialize the database running this command: make init-db.

Here are the required steps to update your playlist with the latest songs from the KSHE radio:

• First, launch the server: make start-api. The app should now be running
  on http://localhost:9999.
• Then, open your browser and go to http://localhost:9999/auth
  to authenticate to Spotify.
• Finally, run make update-playlist to get the latest songs in your playlist.

API

The calls supported so far are:

• GET, localhost:9999/api: Check that the API is up
• GET, localhost:9999/auth: Authenticate for 3600 seconds
• GET, localhost:9999/api/update_playlist: Updates the playlist with
  the latest songs

Web Interface

Writing your own scraper

If you want to add another website to populate the playlist, you can write a new scrapper in the src.scraping module.

Please follow these steps to do so:

• Create a class whose names ends with Scraper, e.g: YourScrapper
  (although it should be explicit which website it crawls).

• Make that class inherit from Scraper

• Call for super() in its constructor, and pass it the URL of the webpage
  to crawl and the playlist_id to upload the songs to. e.g:

  player_url = 'https://radio.com/awesome-song-history'
  playlist_id = '3BCcE8T945z1MnfPWkFsfX'
  super(YourScrapper, self).__init__(player_url, playlist_id)

• Overide the get_song_history method, the first row should be:

  soup, driver = self.scrap_webpage()

• Add your scraper in the tests folder:

  class TestYourScraper(GenericScraperTest):
      scraper = scraping.YourScraper()

• Add your scraper in the src.playlist_updater.Updater class:

  self.scrapers = [
      scraping.KSHEScraper(),
      scraping.EagleScraper(),
      scraping.YourScraper()  # New scraper!
  ]

• You're all set!
