How the Volt Top 50 is built, one day at a time

Each chart day starts from the previous day's edition. The staff moves videos up or down, drops some and adds new ones; a new addition is tagged DEBUT for its first airing.

When the edition airs, a chart day is recorded: rank, last rank, movement, peak and the number of days the video has lived on the chart. There is no Hall of Fame rule and no cap on how long a video can chart.

Premiere timing

The edition premieres at its slot time. If a show is still airing across that slot, the countdown starts the moment that show ends; nothing before a premiere is ever cut short.
