Hey! Check out my new app, an improved music mode for android that captures internal audio instead of recording from the microphone.
Download it from Google Play: https://play.google.com/store/apps/details?id=com.jordigordillo.yeelightmusic

I know I haven’t updated Yeelight Toolbox much while working on this, but development will be resumed. Thanks for your patience!
