The finale of 'Stranger Things' Season 4 utilized iconic Prince songs, 'When Doves Cry' and 'Purple Rain,' during critical escape and resolution scenes. Securing these tracks, particularly 'Purple Rain,' was a significant achievement for the Duffer Brothers, with Matt Duffer crediting Kate Bush's earlier season success for paving the way. The music choices aimed to provide emotional gravitas and resonate with themes of breaking cycles and inherited wounds for the characters.
