Most of them...maybe people would recognize them if they heard them?

I didn't know of the groups A Fine Frenzy and Civil Twilight but I recognized the song "Letters from the Sky" from somewhere. Royksopp is pretty popular at Goth clubs, one of their songs is remixed by an Industrial music DJ. Zoe Keating is someone Leah loves to listen to, she wants to study cello. All the other stuff I would've thought was fairly popular music. Clearly I am mistaken! lol
