Ok, so those three movies aren't great examples, but the point still stands. A large percentage of movies feature a love plot somewhere and at the same time a large percentage of songs are all about love and its many facets."

So your favorite couple is in the middle of a deeply romantic scene. The camera zooms, the lighting is perfect, and the music swells up. Chances are, the music playing is the couple's love theme. May also be designated as such in official soundtracks.
This music can take on several forms, depending on the characters involved, the setting, and the story moment when it is played. It may play over a deeply romantic scene like The Big Damn Kiss or a Grand Romantic Gesture. However, it may also be played over a breakup, a Last Kiss, or when one lover dies in the other's arms. Many themes end up as both a CMoH and a tear jerker at some point. In musical theater, such a theme is likely to show up as Duet Bonding and then repeat instrumentally.
Compare Love at First Note, Dance of Romance, Duet Bonding, and Falling-in-Love Montage.
Subtrope of Leitmotif.
Not to be confused with themed love.
