I've been hearing Kate Bush on the radio for the last two months and when i heard the song snippet in Ep 1 (of season 4) I was puzzled how that could have brought back the song to popularity. Then I got to Ep 4 and I understood! Such a perfect coming together of the character arcs. World building and an amazing performance from Sadie Sink. Great music! Great story and Kate Bush getting rewarded for art ahead of its time - there is good in the world.
