Is Norway's contribution to pop culture the most covered song of all? Quite possibly. Here are some versions in K-pop, a cappella, symphonic, techno, metal, bluegrass, chill, accordion, punk pop. Most are quite good, some are brilliant. Even those that suck are interesting. Personal favorites: A. C. Newman (Of New Pornographers' fame), Aqualung, and Brooklyn Duo.
