This is proof that Abba was much more than disposable pop songs. Such an adult song. Just like all of Fleetwood Mac's Rumors, The Winner Takes It All is written about married couples within the group breaking up. Bjorn wrote the lyrics that his estranged wife, Agneta, has to sing.
I don't want to talk
About the things we've gone through
Though it's hurting me
Now it's history
I've played all my cards
And that's what you've done too
Nothing more to say
No more ace to play
and then later...
But tell me does she kiss
Like I used to kiss you?
Does it feel the same
When she calls your name?
