A woman asks her roommates to play the wake-up playlist. The first song they play is "Havana" by Camila Cabello, which alerts everyone in the house, including a possessed doll. Horrifying events happen when they play the song. They realize the doll and the events are linked to the song but can’t stop listening to the “catchy” song. Spotify says you can listen to "killer" songs on its service for free.
