Winamp to Spotify

I want to tell you about my side project Winamp to Spotify. Digital transformation affected our music listening habits. Before Spotify or any other online music library we used to have mp3 archieves in our hard drives. The aim of this side project is collecting mp3 filenames from harddisk and create Spotify Playlist based on selected folder. So you will be able to listen old songs that you cannot remember.

To use this you need a Spotify Developer Account. To use the Web API, start by creating a Spotify user account (Premium or Free). To do that, simply sign up at http://www.spotify.com After creating a spotify developer account you should register an application through Dashboard.


Creating Application on Spotify API

After these 3 steps your application should be created successfully.


Dashboard view after creating application

After creating you will have ClientID and Client Secret values. After creating app from Edit Settings tab you should set Redirection URLs.


Redirection URLs and other settings

By using https://developer.spotify.com/console/get-current-user/ link you can get your UserID of Spotify User ID.


Getting UserId by calling Spotify API

To make it work ClientID, SecretID and UserID should be placed in exampleappsettings.config file.


exampleappsettings.config file

After setting these config values application is ready to run. You can reach codes from https://github.com/atahanceylan/winamptospotifyforms

I learned Access Token based authorization .Net app by https://github.com/bmsimons/dotnet-core-spotify-authentication github repo. Many thanks to Bart Simons (https://bartsimons.me/)

First step is getting Access Token. After getting access token select folder to process.To simulate Oauth process with callback I used webbrowser code from https://adndevblog.typepad.com/cloud_and_mobile/2016/10/3-legged-oauth-on-desktop-apps-c-winform.html post.

Example folder I selected Black Eyed Peas.From selected folder path I get the Black Eyed Peas as a playlist name. For creating playlist in Spotify I made a post request to https://api.spotify.com/v1/users/{YourUserId}/playlists endpoint.

In project, SpotifyClient.GetTrackUri method created for each track name https://api.spotify.com/v1/search?q={trackname}  endpoint called and Returned trackuri stored in dictionary. TrackUri is unique identifier for tracks in Spotify API.

In project SpotifyClient. AddTrackToPlaylist method created for after getting all trackuri values these tracks added to created playlist. This is done by a post call to https://api.spotify.com/v1/playlists/{playlist_id}/tracks
