Play two videos, use the audio of one and the muted video of another

[Blockaium]

It seems complicated but it really isnt. Take one youtube tab, open a video with music, and open another tab with a video that you will watch but mute it. Then play them at the same time (press [space] and quickly switch to the other video you're going to watch)

Click this, use the audio

Click this, mute it and use the video.
Play at the same time.

Post matching videos and music!
