Ladytron/YMMV

Ear Worm: Much of their work, though especially most of Witching Hour and Velocifero.
Face of the Band: Sort of subverted; While Marnie and Aroyo by far feature the most on artwork/merchandise, as well as both being the main singers, anybody who can name more than two songs by the band can probably tell you who the other members are.
Nightmare Fuel: Some of the music, while not necessarily scary, can be pretty eerie at times. Special mention should go to "Soft Power", "Beauty *2", and "Tender Talons", though.
