If it makes you feel better there are a lot of songs about being or going crazy and most of my favs are on that list. One of the memes I did where you had to post a lyric to fav songs for people to guess made me kind of nervous about myself when I actually *looked* at the finished list.

Also, some of my lists.
Songs about airplanes
Songs about or that mention US states. (mostly Cali, it's popular)
Songs that inculde the name 'Mary' in the lyrics (this one's been going on for years)
Non traditional Christmas Songs or Christmas songs that aren't about Christmas (example, Christmas Card from a Hooker in Minneapolis by Tom Waits)

I'd like to see some of the songs on your superman list if you don't mind.
