Youtube implements new scheme for its channel. One Google account can have multiple channels. And one channel can be organized/managed by some accounts. It sounds good. But the problem, when you have assigned a channel to a Google Plus/Google Page account, you can't change back to other Google Plus /Google Page accounts. Yeah, I have that problem, my primary Youtube channel can't be linked to my primary Google Plus account because I have set a Google Page to my Youtube channel before. So, I decided to tidy up my channel and create some channels. For guitar or music performance I make it on Allegro. And this is my guitar playlist.
