Sure. It's a shorthand I use to describe movement somewhere on the web. This is based on using the free Bluesound app BlueOS, which I forgot to mention (sorry!). I'm betting there's Tidal or Spotify or Amazon have similar functionality.
1) It means I listen to Radio Paradise and hear a song I like.
2) I go to that song on Qobuz (one click if you have the Bluesound app)
3) I then go to the artist's page on Qobuz via their "Go to Artist" function (again, one click.)
4) Once at the artist's page, Qobuz automatically suggests other artists (one click on their "Similar Artists" feature)
So now you have a bunch of similar artists to explore in three clicks.
Does that make more sense?
