Earworms... Don't Break Out The Duct Tape

I had a weird episode of having a song stuck in my head the other day. It wasn't just one song, but several songs with similar elements. It went from "And I am Telling You I'm Not Going" to "I am Changing," both from Dreamgirls, to "I Have Nothing" by Whitney Houston, to "Love Will Lead You Back" by Taylor Dayne. It was weird. It was like a loop where one part of one song just becomes part of the other song, I couldn't separate them, or get past the point of the loop. It was very disturbing. Maybe if I knew how those Dreamgirls songs went all the way through...
