I would really like to be able to view ALL of an artist's songs. Right now, you need to click on each album to see what songs are available which is really frustrating. There's a "Show More" button for albums and singles but not for popular songs.
Right now, you can only view all songs from an artist by heading into their albums and singles. As a workaround, you can view all songs from an artist, by searching for the artist and clicking on tracks. I recommend you to submit this as an idea on the Ideas board. Let me know if there's anything else. 🙂
