New Musical Fic

I am currently in the works for "Procrastination For My Contest Stor-" I mean a new musical project. Seeing as how my last musical project was...awful. I decided to make a parody of musicals as a whole. The idea originally started out as the 3rd fic in the Trixie series and the plot was everypony was forced to live in a musical but I thought it would be anti-climatic. This new fic is about Twilight Sparkle's struggle to write a musical while all her friends are adding suggestions for it. But first, I would like to ask you something, have you seen a fic like this? Because I don't want to rip off anyone's story here. Anyways chao faithful viewers and tell me what you think!
