RE:RE:RE:RE:RE:RE:ABBAYes. I've heard David Geffen and other top music people say that.
Another fun ABBA fact...in 1974 when they came out with Waterloo and made it big. Agnetha couldn't even speak english. Benny composed the music and Bjorn told Agnetha to learn the words phonetically in english. He was so smart he knew to reach a wider audience they couldn't sing in Swedish.
