{
  "SoundCloud_Username": "",    // SoundCloud User Name (These are the playlists to sync)
  "SoundCloud_ClientID": "",	  // SoundCloud ClientID (leave empty for automatic setup)
  "Deezer_Secret": "",          // Login to Deezer and search in the dev console for an arl Cookie
  "Spotify_Username" : "",      // Spotify User Name (These are the playlists to sync)
  "Spotify_Secret" : ""         // Spotify Bearer API Key
}

The Search Engine is splited in two parts:

1. The Deezer Search:

   It´s to get a list of songs out of Deezer that might contains the right song.

2. The Result Search:

   It´s to find the right song in the Deezer search results.

The perfect Search flow should look like this:

1. Execute Deezer Search Stage 1
2. Gets a valid result with multiple tracks
3. Execute Result Search Stage 1 to find the right song
4. Return song ID

Note: A Deezer Search Stage triggers all Result Search Stages

The Deezer Search is build up in three stages. Every stage is a indipendent search query you have to get an empty result in order to jump through the stages.

1. Prepare search query remove unsearchable chars such as (& < > ( ) [ ]) and detect if the song is a remix and save the remix artist as an extra artist

2. Artist changes, split song title at first - char and replace it with the possible remix artist or with the SoundCloud user name.

3. Search only with song name (without the artist name) and duration
