Simple project using AutoVoice and AutoInput to Thumbs Up or Thumbs Down and song.
Straight away, this project uses Google Play Music for the default app to work with. But, you can just plug in your own music app, like Pandora, and adjust the AutoInput action using the "easy setup" feature to select your app.
I made this becuase I couldn't find a simple intent to for the thumbs up/thumbs down feature of most music apps. It's useful while driving becuase the icons are just to small to find carefully.
