Songs have been written about every topic imaginable, but the best ones -- from swooning '50s ballads to contemporary club bangers -- have been penned about the ups and downs of being in love. We are counting down the top 50 Hot 100 hits with a form of the word "love" in the title. The romantic tunes cover all seven decades of the Hot 100's history, ranging from 1958's "To Know Him Is to Love Him" by the Teddy Bears to 2011's "We Found Love" by Rihanna. It's sonic proof that while musical fads and fashions will change with every generation, love -- and the songs inspired by it -- will never go out of style.

The ranking is based on actual performance on the weekly Billboard Hot 100 chart. Songs are ranked based on an inverse point system, with weeks at No. 1 earning the greatest value and weeks at No. 100 earning the least. To ensure equitable representation of the biggest hits from each era, certain time frames were weighted to account for the difference between turnover rates from those years.
