Isn't it Ironic?

Music and me = inspiration.  As far as writers go, that's nothing new, but once in a while a song will come on the radio and make you immediately think of your MC.  (Not "This made me think of something new to write", but "This is exactly like a person I'm writing or have already written about".)

Today it was Ironic, by Alanis Morissette.  Totally made me think of Calli, the main character in my WiP. (Ironic, isn't it?)

Has that happened to you?  Do you have a song that could practically be the theme for your MC?
