Somewhere, Kate Bush is remembering Stranger Things stratospheric boost of Running Up That Hill and nodding in recognition. But the songs suddenly re-popularized in the wake of Severances second season finale are even older than her 1985 pop hit. That includes the stirring rendition of The Windmills of Your Mind that plays as Mark S. and Helly R. are sprinting into their uncertain future, and the jazzy Work Song that plays over the Cold Harbor end credits. Both of these songs are standards that have been oft-recorded over the years. Windmills is specifically Mel Torms 1968 version, while this take on Work Song is Bobby Darins from 1963. So these are not exactly ditties thatve charted recently until they became swept up in the Severance phenomenon, that is. As Billboard reports, in the four days since the finale aired March 20, Windmills has since racked up 215,000 U.S. on-demand audio streams, which represents a 30,000% increase since the previous week. Work Song was streamed over 20,000 times, which is fewer than Torms track, but is a 35,000% increase from the same span of days in the previous week. In addition, the Alan Parsons Projects Sirius, notable for its use by the Chicago Bulls for player introductions during the Michael Jordan 90s heydayand now forever linked with Mr. Milchicks MDR celebration after Mark S. finally finished the Cold Harbor filegot a 16% boost to just under 125,000 streams. So far, theres no word on where we can stream the Choreography & Merriments marching band versions of Lumons most stirring anthems. Want more io9 news?
