This reminds me of the iTunes CD covert art trend mid 2000s. I dug up this one that still seems supported.
TunesArt is the perfect companion for iTunes and Spotify on macOS: display an album cover on your desktop, download lyrics, quickly search your music library, share on Last.fm and Twitter, and control your player...

CoverSutra was the big name in town but I recall there was another free alternative that was pretty snazzy too.
CoverSutra gives you a handy -- and attractive -- way to control iTunes without having to leave your current app.
