Honestly? It is a horrible show, if you ask me. But it may be a good move for Grace and the Nocturnals. I may not watch the show anymore, but after having bought the duet between Grace and Joy, I found myself wanting to get "This is Somewhere". This is obviously not a Nocturnals song, but I like it. 

And I am a Joy fan, so it is safe to say, that this isn't a Joy song either. Her music tends to be a little more calm and as she has said herself, her lyrics tend to be a little dramatic, so I would rather have wanted Grace and Joy to do a duet with their own styles, but this is solely for the show, I think. 

The songs Joy have performed on the show as Haley tend to be more pop-like, and this duet does, too.
