1 disk each week was assigned bonus points equal to the total number of positions on its respective chart.
Unfortunately, Billboard's late December print deadline prevented approximately 60 records from completing their full chart runs, and their formula also included approximately 50 records from 1963, some of which had enough points to rank in the 1964 chart.
The complete chart life of each record is represented, with number of points accrued.
The chart can be sorted by Artist, Song title, Recording and Release dates, Cashbox year-end ranking (CB) or units sold (sales) by clicking on the column header.
