What type of genre is 1234 by Feist?

Folk/pop

The recording uses folk instruments like acoustic guitar and banjo, but its emphasis on groove would put it more in the genre of dance/pop. The production also sounds heavily "Europop" -- dance/pop music with orchestral and big-band touches -- putting it in league with European dance acts like Saint Etienne, early Rick Astley, or even Natasha Bedingfield, or Abba.
