Technically, they already are. They claim the rights to your videos and put ads on it. They just aren't following the traditional YouTube model of deleting the video along with all similar ones and placing a strike on your channel. I personally believe that this is a better way of handling it. Also, I can't think of a single time where YouTube has made progress in some way like this, then 'regressed' into a worse form of the past. I think there's little concern of Nintendo taking legal action against you.
Can that device notice the song if it's under 15 seconds?
