Actually while I can't find the exact citation(probably because I'm not bothering to look it up), when I was in training by Dodge, they admitting use of subliminal advertising, altough it was rather blatant. Anyway during this training was something K-Mart used. After certain studies they decided to start playing certain music over the intercom to reduce shoplifting. Within 6 months there was a huge decrease in theft. In some stores they went back to standard pop culture and the shoplifting went back up. With more studies they tried other musics and found they increased shoplifting above normal amounts. Something to look into.
