Also worth noting is that it’s only available to your primary YouTube account. For me that somehow became a different one created when they foisted Google Circle on everyone. So my actual YT account, that I use every day and matches my email address, can’t access my saved YT music. I have to change YouTube profiles to listen to it, which I do on occasion.

Sure it sucks, but it can’t be a surprise anymore.
The username @X was also taken from a user. Same with @Music, who if I recall correctly, was a fan of Musk and was even subscribing to Twitter at the time. They even continued to do what @Music was doing with music recommendations, so it was barely a rebrand. It was basically just hijacking the work someone else put into establishing their social media presence.
