Sometimes you find soul in the most unexpected music. Even in popular music, which, it seems, should be completely commercial and smell only of money. Although, perhaps, it was the very soulfulness that was popular in the seventies (I am not very familiar with the music of this period).
This wonderful group, which once won Eurovision with the song Ding-A-Dong, performs quite simple, pleasant, and cheerful music, which various sources attribute to the genres of pop and dance. I recommend listening to songs such as: Ding-A-Dong, Russian Melody, Play It High, especially the latter, which resembles a short fairy tale.
