With which song did ABBA win the 1974 Eurovision Song Contest?

They play haunting music that is kind of folksy. When I first heard them the jouvial ( Dancing Queen) it sounded soulful and upbeat. I wondered if they were an American group. Most of their music to me is lovely and ear pleasing while danceable. ! ! !

Very distinctive sound with great lyrics and music.

I love their songs and music, Mama Mia ❤ is a wonderful movie 🎥 and musical 🎼 I wonder how much they would have done if they didn't break up?

Loved their music in the film Muriel's Wedding.
