What is Betterify?
Betterify is an open source Spotify modification currently only supporting themes. This is currently a novelty as there is no way (yet) to make it automatically trigger. This modification does not allow everything yet. You must have chrome installed.
The default unconfigured Betterify theme.
Usage
Step 1
Download the latest release here.
Step 2
Enable debugging in Spotify. To do this right click on your Spotify shortcut and add --remote-debugging-port=9222 to the Target and click ok.
Step 3
Open devtools. Open Google Chrome and go to chrome://inspect. Then wait for Spotify to show up, then click inspect. Drag the file you saved in Step 1 to the console input and press enter once the text shows up. Now it's done, close Chrome and enjoy your themed Spotify (until you close it)!
