In 1985, English singer-songwriter Kate Bush released a song called “Running Up That Hill.” It did pretty well — reaching No. 30 on the Billboard Hot 100 in the US. But 37 years after its release, the tune — featured in last week’s episode of Netflix’s “Stranger Things” — bumped Harry Styles’ “As It Was” to No. 2 on the US Billboard Top 10. The unexpected success also makes her both the oldest and the youngest woman to have a self-written No. 1 in the United Kingdom, Billboard reported.
