Input: Question: How long had TikTok been in existence for the year Old Town Road first entered the Billboard charts? Passage: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.
