Released on Aug. 7, 2019, rock band Tool's titular single from their new album Fear Inoculum currently holds the title, clocking in at a length of 10 minutes and 23 seconds. It debuted at No. 93 on the Billboard Hot 100, the first song by the band to make the chart since "Schism" in 2001. When the album released on Aug. 30, 2019, it debuted at No.1 on the Billboard Top 200, a major success for the rock genre, and of course for Tool, especially considering that it was their first studio album in 13 years.
Previously, David Bowie's "Blackstar" from his final studio album of the same name held the record for the longest song on the Billboard Hot 100, with a length of 9 minutes and 57 seconds.
