I also recommend going to https://www.youtube.com/feed/music . It's a landing page that used to be behind a "Music" button on the youtube homepage, but has since been removed. But luckily the page still exists. It gives you a bunch of different playlists, including "Recommended" and "Latest Videos". I like the Latest Videos because it allows me to see what's "current" at a glance, even if I choose not to view any of them, I can see what' going on in the mainstream.
