Correva l’anno 1987, Il Mercy iniziava a merciare, i singoli si compravano ancora sotto forma di dischi a 45 giri ed il duo Pop Rock dei Roxette dava alle stampe It Must Have Been Love.

Nel 1990, la canzone viene inserita nella colonna sonora della commedia strappamutande con Julia Roberts e Richard Gere, Pretty Woman. Lì vive una seconda giovinezza e raggiunge il successo internazionale.

Il testo di It Must Have Been Love, che in italiano significa “Deve essere stato amore”

Lay a whisper on my pillow
Leave the winter on the ground
I wake up lonely
There’s air of silence in the bedroom and all around

Touch me now
I close my eyes
And dream away…

It must have been love but it’s over now
It must have been good but I lost it somehow
It must have been love but it’s over now
From the moment we touched ’til the time had run out

Make-believing we’re together
That I’m sheltered by your heart
But in and outside I’ve turned to water
Like a teardrop in your palm

And it’s a hard
Christmas day
I dream away…

It must have been love but it’s over now
It was all that I wanted, now I’m living without
It must have been love but it’s over now
It’s where the water flows, it’s where the wind blows
