The Web Player for Spotify™ extension is a Chrome application to load the official Spotify web player inside an isolated window. This application can be used instead of the desktop version of Spotify as it supports almost all the desktop version's features. Note that the web player is loaded in an isolated (sandboxed) window which cannot interact with your browser hence you need to login into the player one more time. For extension version, there is an isolated iframe instead of webview and hence there is no need to login again if you already logged-in in your browser once.
