I don't get the point. What would be different from using music explorer node?
Unless I have not been able to find these options, in the music explorer you can't use the thumbnails browser, and can't hide the column with the most played/rated songs.
(By the way, adding these options to the explorer would make me very happy
)
I do not intend to add the music explorer options (like artists, profile, etc.) to the main panel.
I propose to use only the aesthetics of music explorer (the bar and the photo of the artist, and maybe the genres and years) as an alternative to the photo of the artist that you propose. So I've used your mockup.
