Absolute pile of trash. As usual with Google they've decided to kill a perfectly good thing (GPM) and introduce a monstrosity for absolutely no reason. The UI is trash, integration of a personal library/uploads makes no sense, playlist sorting makes no sense, alphabetization of artists is dumb (how have we not learned that bands that start with "the" don't go to T), and the functioning on the new Chromecast is abysmal. There does not seem to be a way to search just music in YTM on the Chromecast, with search results including primarily live performances rather than populating search results with albums, singles, etc. Once again, this is an absolute pile of trash. After years of refusing to use Spotify because GPM was actually a good app, I'm immediately transitioning to Spotify.
