Has a song ever been #1 on the Billboard Top 100 singles’ chart, fallen from the top spot (but remained in the Top 100), only to climb back up to the #1 spot? Even a drop to #2 and then back up to #1 the following week?
If it’s happened more than once, what was the biggest drop for a song from #1 before returning to the top of the chart?
(I’m not talking about a song that may have gone #1 and then was rereleased at some later time and hit #1 again. Only songs that never left the Top 100 before returning to the #1 spot count.)
