Only song to be number 1 on the charts go off and be number 1 again?

The only song to achieve the feat of reaching number one on the charts, dropping off, and then returning to number one again is "Old Town Road" by Lil Nas X featuring Billy Ray Cyrus. The song initially topped the Billboard Hot 100 chart for 19 consecutive weeks in 2019, then fell off before reclaiming the number one spot later that year. This unique accomplishment highlights the song's massive popularity and cultural impact.
