Not ABBA, but one of my favorite Swedish performers, is Sofia Jannok.
This was one of her best displays of the sweet, innocence she had. BTW it features the Ice Hotel near where she lives.
This one was also great but I especially like the Caddy. Notice how the innocence is...fading.
Today she still has a great voice but is far left in everything and her music is suffering. I suspect she is in with the wrong crowd.
No doubt the innocence is fading. The culture is being diluted. Leftism destroys everything eventually.
