You can also find them listed here: Billboard Top 100 Songs of Every YearI have been maintaining a list of the Billboard Top 100 for every year (ever) since I started gigging. Note that in the 1940s and 1950s it was only top 3o lists I believe but those have limited use as that generation slowly ages out. Lately i have been adding the Ryan Seacrest top 40 lists to keep current for dance/modern music....

For mainstream lists, if they ain't on these lists, they ain't relevant (Ok, very partially true) ;-)
As an aside, I keep those all on a tablet as my get out of jail free card if my laptops or system ever craps out. I can always direct insert into the back of my speaker mixer from an extra long 3.5mm y cable to stereo RCA. Did that once and it saved my bacon for 10 minutes until I got things back up again at a wedding a couple of years ago!
