Input: Question: How many active TikTok users were there the year Old Town Road entered the Billboard charts? Passage 1:The song initially gained popularity on social video sharing app TikTok and eventually entered the Billboard charts in March 2019. The song reached number 19 on the Billboard Hot Country Songs chart before the magazine disqualified it from being included on the chart on grounds that it did not fit the genre, sparking a debate on the definition of country music. Though the song was not re-entered onto the overall country charts, both the original version of the song and the remix featuring Cyrus eventually peaked at number one on the flagship Billboard chart, the Hot 100, for a record-breaking nineteen consecutive weeks. Internationally, one or more versions of "Old Town Road" have topped the national singles charts in Australia, Canada, France, Germany, Ireland, the Netherlands, New Zealand, Norway, Switzerland, and the United Kingdom; and charted within the top ten in various other markets. Furthermore, the song was awarded diamond certification by the RIAA, in October 2019, for moving ten million total units in the United States, the fastest song to be awarded diamond certification. The remix of "Old Town Road" featuring Billy Ray Cyrus has been nominated for Record of the Year and Best Pop Duo/Group Performance at the 62nd Annual Grammy Awards, with its music video receiving a nomination for Best Music Video.
Passage 2:Another common use of the theme is as a prison for villains or demons. The idea is used in the first two Superman movies starring Christopher Reeve where Kryptonian villains were sentenced to the Phantom Zone from where they eventually escaped. An almost exactly parallel use of the idea is presented in the campy cult film The Adventures of Buckaroo Banzai Across the 8th Dimension, where the "8th dimension" is essentially a "phantom zone" used to imprison the villainous Red Lectroids. Uses in horror films include the 1986 film From Beyond (based on the H. P. Lovecraft story of the same name) where a scientific experiment induces the experimenters to perceive aliens from a parallel universe, with bad results. The 1987 John Carpenter film Prince of Darkness is based on the premise that the essence of a being described as Satan, trapped in a glass canister and found in an abandoned church in Los Angeles, is actually an alien being that is the 'son' of something even more evil and powerful, trapped in another universe. The protagonists accidentally free the creature, who then attempts to release his "father" by reaching in through a mirror.
Passage 3:The government of the Electorate of Hesse (Kurhessen) had begun building the FrankfurtBebra railway from Bebra in North Hesse to Fulda, Hanau and Frankfurt before its annexation by Prussia after the Austro-Prussian War of 1866. The project was completed by the Prussian state railways on 15 December 1868. Until the opening of the line south of the Main, trains from Bebra to Frankfurt had to use the North Main line and the Frankfurt City Link Line. On 15 November 1873 the new line south of the Main between Hanau and Frankfurt via Sachsenhausen and Offenbach was opened, including South Station (opened as Bebraer Bahnhof, "Bebra line" station) and Offenbach Hauptbahnhof. The South Main line is still the most important rail link connecting Frankfurt with Leipzig, Berlin and Hamburg.
