The last three shows I've worked on have all, in some way shape or form, included the song "Single Ladies," and it now seems permenantly embedded on my psyche (unfortunate as that is). In addition, my inner DJ keeps mixing it with "All That Jazz," and "Rule Brittiana," both, also, from the current show. Ocasionally my brain will jump tracks in the middle of a line, or put lyrics from one song on the tune of another, and it's really getting annoying.
What musical mayhem is your current show wreaking on your brain?
