What did 'Stranger Things' do to Kate Bush and Metallica?

“We’ll be hearing about it for the next 10 years at least, in terms of a reference point in marketing meetings” - Jonathan Palmer of record label and music publisher BMG, said about the "boom" of Kate Bush's 'Running Up That Hill' after being used in 'Stranger Things'. The same is happening with Metallica's 'Master of Puppets' since being used in the show's finale earlier this month. Last year we've seen a similar pattern with TikTok. "The triple bonanza of a TV sync spiralling into music streaming services and TikTok is something that cannot be orchestrated though, only capitalised upon" - Guardian points out.
