YouTube Music still has this feature and it even uses the die icon, just like always.

You can also do this in YouTube Music.

They rebranded the exact same code base with largely the same staff. I don't know why you perceive this to have been a break.

This is actually completely false. (Source: I worked at Google at the time this transition was made, though not on GPM or YTM).

Two completely different codebases and teams and in fact YTM launched missing a boatload of features that Play Music had. Including annoyingly the ability to use our own Chromecast features on the desktop/browser version. (I worked on the Cast team). There were quite a few angry internal buganizer tickets.

Yeah, but if the songs in your Google Music library weren't on YouTube Music, you just lost them forever. End of story.

It was the betrayal that turned me off Google.
