Motivation

After the announcement that Soundrop would be closing its doors, I was unable to find a suitable alternative. Some alternatives use Youtube, but the sound quality is often poor. Some also use soundcloud, but not all tracks are available. Since Spotify are removing all apps in the desktop, the only way to build a "clone" of Soundrop was to build a native client, using their official library libspotify.

Libspotify is limited to premium accounts only, but for now is the only option (until their web api supports deeper control e.g. track seeking etc). Since the majority of Soundbounce is a web application, this transition could be made to being 100% browser-only in the future, but for now we need a native client.

Known issues

Sometimes audio won't work on first launch. Wait a few minutes, restart app and should be fine from then on. Seems to affect OSX more than Windows.
If you get spotify credentials wrong, you'll have to re-launch app

Technology used

libspotify & libspotify.net to connect to Spotify
naudio for sound output
Chrome Embedded Frame (and CefSharp) for all UI
WinForms to host the ChromiumWebBrowser
React / JSX for front-end
node.js for the server, keeps all data in memory and stores in simple JSON files
Express webserver, websockets & passport for social integration
Spotify Web API used on the server to lookup tracks, and load playlists
