"Unspeakable" is a single from Ace of Base's 2002 album Da Capo.

The single peaked at number 3 in Israel, 14 in Finland, 45 in Sweden and 97 in Germany.

The video features a taxi driver driving a Citroën DS cab through Stockholm during a night shift, listening to the song on his car's radio.

The driver ends up picking up two passengers, but doesn't realize they are Ulf and Jenny, who start singing along during the ride.

Eventually, the taxi driver arrives back home at the morning light, then turns on the TV, where the music video is playing, finally showing the driver.
