Since 1974, when a little-known group named ABBA won Eurovision's song contest with their track "Waterloo," Sweden has been a global force in exporting pop music. Cassette players and bedroom walls have been filled with the likes of Roxette, Ace of Base, and Robyn, and '90s playlists featuring Britney Spears, Backstreet Boys, and *NSYNC would be obsolete without the work of Swedes Denniz Pop and Max Martin. Today, Swedish producers and songwriters continue to be the powerhouses behind the biggest pop stars. Featuring interviews with ABBA's Benny Andersson, Ace of Base's Ulf Ekberg, and The Backstreet Boys' Brian Littrell, this episode explores how one - Scandinavian country came to dominate global pop music.
