I (@Shpigford) have been a longtime iTunes user and, despite its shortcomings, the ability to build complex, dynamic playlists has yet to be matched by the other streaming services.

I desperately want that ability in Spotify, so PLYLST is my attempt at building the thing I think it's missing most: that ability to put together dynamic playlists based on many different attributes.

The codebase is vanilla Rails, Sidekiq w/ Redis, Puma, and Postgres. Quite a simple setup.

1. You'll need to pull down the repo locally. You can use GitHub's "Clone or download" button to make that happen.

2. Then, add a config file to config/application.yml with Spotify OAuth keys. See below on how to get setup and get keys for Spotify.

spotify_key: KEY
spotify_secret: SECRET

You'll need a free Developer account, which you can create here: https://developer.spotify.com

Go into your dashboard, create a new app or edit the settings on an existing app and set the Redirect URI to http://localhost:5000/users/auth/spotify/callback

These will get you the necessary keys for the app to fully function.

If you'd like to pull in lyrics for lyric-based rules, you can create an API key here: https://genius.com/developers

The "Client Access Token" is the key you want. Genius is only required if you want to build/test rules around lyrics.

3. In the command line, you'll then run the following to set up gems and the database...

$ bin/setup # Installs the necessary gems and sets up the database

4. Finally, start the server (also in the command line)!

$ foreman start # starts webserver and background jobs

If you don't already have foreman installed, you can install it with gem install foreman

It's still very early days for this so your mileage will vary here and lots of things will break.

But almost any contribution will be beneficial at this point.

If you've got an improvement, just send in a pull request. If you've got feature ideas, simply open a new issues!

One area that can always use some additional perspective is performance.

You can see what the current painpoints are on Skylight.
