kidnapster
Someone who abducts children by enticing them with music.
Professional toddler-stealers in the early 20th century like Georgia Tann and Bessie Bernard were notorious for luring children with things like candy and offers of car-rides; one wonders if they could have done even more harm if high-quality audio-systems had been invented by the time, and thus appealiong-sounding tunes could also have been used to attract children, these shameless human traffickers therefore could have become kidnapsters, as well.
