"We're in the building where they make us grow, and I'm frightened by the liquid engineers, like you."

For this episode, I look back at one of Gary Numan's best-known and best-loved songs, 'Metal', from 1979's The Pleasure Principle.

The track was the first song on the album with lyrics, and was inspired by the writings of Philip K Dick, about a machine with a desire to be human.

The perfect synthpop track was never a single, but it became one of Gary Numan's most-performed songs, and was later covered and sampled by a number of artists, most notably by Trent Reznor's Nine Inch Nails.

The episode looks at:

• What 'Metal' is all about
• Its somewhat forgotten music video
• Why it was never released as a single
• The various live versions
• When Gary performed it with Nine Inch Nails in 2009
