I'm a closet ABBA fan...

I thought the Swedish Hitz guy could have gone heavier. It's too close to the original imo. It's not that the original is bad or anything, but if you're going to do a metal cover of a pop/disco song then it should scream "THIS IS NOT A POP SONG!" Same applies to a rock cover. 
Mama. Agreed.

When ABBA was very populair in the 70's, I liked them.
Now after all those years there's music and bands I like much more.
