Before ABBA became one of the most successful groups in music history, they were four talented musicians hoping the world would hear something special in their sound. Their breakthrough came in 1974 with a song that was bold, theatrical, and impossible to forget: “Waterloo.”

The song told the story of surrendering in love, using the famous battle as a playful metaphor. With its infectious melody, sparkling harmonies, and unforgettable stage performance, it stood apart from the more traditional entries at the Eurovision Song Contest.

When ABBA performed “Waterloo” in Brighton, England, the group won the competition—and their lives changed almost overnight.

The song became an international hit, introducing their name and sound to audiences far beyond Sweden. It marked the beginning of a remarkable journey that would eventually bring the world classics such as “Dancing Queen,” “Mamma Mia,” and “The Winner Takes It All.”

But there is an intriguing question behind every successful song: does the artist always feel the same way about it as the audience?

A group may create a hit through a mixture of instinct, collaboration, and a little good fortune. Yet the song that becomes a public symbol of their success may not always be the one they personally hold closest to their hearts. Artists grow, their tastes change, and the meaning of a song can shift over time.

There is no reliable confirmation that “Waterloo” was ABBA’s least favorite song. Still, its story reveals something important: a song’s destiny is not always decided by the people who create it.

For ABBA, “Waterloo” was the door that opened to the world. It may not have been the final word on their artistry, but it gave millions of listeners their first reason to fall in love with the group.

And sometimes, that first song becomes a memory that never fades.
