A few weeks ago, I posted about a YouTube experiment that adds bigger cards for music artists. Search for Röyksopp, Daft Punk or any other popular artist and you'll see a Knowledge Graph-like sidebar with a list of top tracks, albums and related artists. Click any track and you'll start a playlist with a lot of other songs from the same artist. Click an album and you'll be able to listen to all the songs from the album.
What else is there? You can also click "top tracks" to start the playlist automatically generated by YouTube. Click the artist's name to visit the topic channel created by YouTube (there's no topic channel for Röyksopp, but there's one for Daft Punk).
