When you get an Official Artist Channel, we merge subscribers from your topic channel and your existing channel onto your new channel. You may see an increase in your Official Artist Channel subscriber count as we consolidate your audience.
Your subscribers will get your new music videos, whether they subscribed to your Official Artist Channel or your other channels. This merge should help you promote and distribute new music more effectively.
Fans now have a single place to subscribe — your Official Artist Channel. The subscribe button and subscriber count will no longer be displayed on your existing channel or topic channel.
