It may be a little too obvious a way to go since it was my first thought. But it seems like Behind Blue Eyes could be a song to use to get insight into a 'villain'. Nobody knows why, until Doug comes along and uses the song to get effectively a series of flashbacks of points in the persons life that caused them to take their current course of action. The downside being that the target knows what is happening (although if they their disbelief in magic or telepathy is strong enough they might not believe its actually happening), and is most likely quite ticked off at the invasion of their past.
