Here are the Top 15 best English-language songs excerpted from movies according to AFI.

What may have been the best-selling single in the entire history of music? This record belongs to an obviously very famous song, composed many decades ago but still very topical. We hear it every year, as do all the top 10 best-selling songs of all time.

The calculation has been split in two, due to the advent of technology, downloads and Spotify streaming, which have 'drugged' the market and made the previous charts truly obsolete.
