I just received this e-mail from YouTube:<p>Hi music fans,<p>When you want to follow an artist on YouTube, sometimes you’ll find that they have multiple channels. So, which one should you subscribe to?<p>To make things simpler for fans, we worked with artists to unify their songs, albums and videos under one Official Artist Channel. Your artist subscriptions and notifications will soon move to Official Artist Channels and you'll be able to manage Official Artist Channel subscriptions like any other channel subscription. Your current secondary artist channel subscriptions will become inactive.<p>By giving you one artist channel to subscribe to, it will be easier for you to keep up with your favorite artists and their music!
