Paul McCartney is about as at home on the Hot 100 as an artist can be. From the Beatles' record-setting 71 singles on the Hot 100 chart to McCartney's nine post-Beatles No. 1s, his songs are all over the Billboard history books.

Paul McCartney: The Billboard Cover Story

Now, in honor of Sir Paul's 70th birthday (June 18), we've compiled a list the 40 biggest Billboard hits from his nearly 50-year career. The ranking includes not only Wings hits and Macca duets with Stevie Wonderand Michael Jackson, but the Beatles' biggest chart-toppers -- some of which Paul wrote, others that he simply contributed to as part of the great Lennon-McCartney songwriting duo.

This chart of Paul McCartney's 40 biggest Billboard hits is based on actual performance on the weekly Billboard Hot 100. Songs are ranked using an inverse point system, with weeks at No. 1 earning the greatest value and weeks at No. 100 earning the least.
