A Windows application that synchronizes what you're listening to on Spotify with Soundpad so that you can play music through your microphone in VRChat (and any other game).
Download and extract the ZIP file. Launch Spotify, Soundpad then my app. When you play a song in Spotify it should detect the change (checks every second), pause the song, download the song from YouTube, add it to Soundpad then play it.
When Soundpad is near the end of the current song it will play the next one in Spotify. This feature isn't 100% perfect but it works okay.
Tested on Windows 10 64 bit only.
