"Pop Trash" continues where "Medazzaland" (1997) left off; elements of rock, synthpop and electronica fused together, with many layers of production. The album is probably one of Duran Duran's most diverse, with songs like "Lava Lamp" including flanged drums and intricate guitars, the catty "Mars Meets Venus" and bizarre "Hallucinating Elvis" full of manufactured bounce, while gentle pop ballad "Someone Else, Not Me" featured few effects at all. Heavy guitar pieces like "Last Day on Earth" and "Playing With Uranium" are juxtaposed with softer songs filled with delicate melancholy, like "Lady Xanax" and "The Sun Doesn't Shine Forever".
