Adds a MP3 Download button next to the subscribe button, thanks to youtubeinmp3 for their simple download service (http://youtubeinmp3.com/api/). Based off magnus's youtube2mp3 code. Just used something different as it wont open another tab.
< Feedback on Youtube MP3 Download Button
I've been using this for the past year and it works just fine as of 2016-05-27 :smile:
Script no longer works
Button shows, redirect says "Video not found"
