Billboard publishes the Hot 100 list every week.
Over a year's time, there must be several hundreds of songs that appear on that list.
At the end of each year, Billboard publish an annual Hot 100-which is easy to find.
But how can I find a compilation list of every song that hit the weekly charts for a given year?
Put another way, I don't want the weekly list as it contains duplicates, but rather I want a list of every song to appear on any of the weekly lists yet I want such song listed only once.
Any ideas where to find this information?
