The best disco songs are fueled by not-very-double entendres. Goldfrapp has dabbled with success in various styles of music, but they’re at their best when they’re time traveling us back to the era of spandex on the dancefloor. That kind of unabashed sleazy fun may go out of style, but it never stays out of style for very long. People just want to dance to songs about rockets. Rockets are sexy, you see. They represent the unbridled libido. The promise of going to metaphorical outer space on a metaphorical rocket is why people go to the disco. The music that takes them there doesn’t get a lot of credit for its cultural value, but it does its job. A purveyor of really good dance music will always be in demand, and artists like Goldfrapp, who take those vintage four-to-the-floor grooves into the 21st century, deserve acclaim.
