On Chart

On Chart (abbreviated as OC) is the running count of weeks an album has spent on the King Warz Charts Top 20 Album Charts up to and including the listed week. It appears as a column in the weekly album tables and in the Chart History table on every album page.

Key Features of OC

• Cumulative count: each charted week increases the value by 1, no matter how large the gap since the previous appearance.
• Longevity measure: a high OC value marks an album as an enduring favorite rather than a one-moment release.
• Song equivalent: the songs chart tracks the same statistic under Weeks.
