I'm not sure why there are so many super heroes and villains with doctorates, but there seems to be, and Dr. Strange is one of the better ones. Although only some of these songs are psych, they all make for good listening while staring at a black light poster. So that may be the organizing principle. If there are other highly educated Marvel character besides Dr. Doom and Dr. Octopus, feel free to leave a comment and some helpful info.
