*  Here is how Duckhead calculated this chart from Radio and Record charts.

Points
Points for the yearly charts are calculated using inverse points from the weekly charts.
Each week, the # 1 song gets 20 points, the # 2 song gets 19 points, # 3 gets 18, and so on.
The # 20 song gets 1 point.
Each song's points are added up for each week to reach the total.
A song's entire chart run will be used for the yearly chart.
Songs appear on the yearly chart corresponding to the year they peak on the weekly charts.
Tie-Breakers
For songs that tie in points on the yearly charts, the following tie-breakers are used:
1. Most weeks at # 1
2. Most weeks at # 2
3. Most weeks at # 3
4. Most weeks at # 4
5. Etc.
If songs remain tied after all 20 tie-breakers, then they will be listed as tied on the yearly chart.
Tied songs appear in alphabetical order, and are marked by letters, for example: 99A and 99B.
