Cheers dude!
Yeah, whatever we choose to do, what would be good is to keep only one version of each video on YouTube. For example, I would upload a sonata on my channel and then, through some witchcraft, the same video can be linked to this new account / playlist (whichever way is best). Then if someone listened to a piece in a shared YC playlist on YouTube, then another piece by another YCer would autoplay afterwards! Everyone should get more views and subscribers. Genius! :P
