Wow, how can you not know this feature was in there, Jo, it's been included for at least 3 years now!

Anyway, since this method gives you the chords right into the video, it could potentially make those "educational" clips of your cover songs a whole lot simpler to make

p.s. I know you were just whipping out those two demos real quick for the sake of showcasing the feature, and that you're obviously busy with other things, and I'm nothing but a big nitpicker here and yadayada, but well...both of them have the wrong chord at the end
