The 'message' seemed painfully forced, it honestly comes out of the left field. Additionally, the audio was SO bad that I couldn't try more than twice. I kind of understand you might have been trying to go for 'realism' but if you've ever heard a group of workers sing, they get in near perfect sync, so it actually makes no sense for them to be so far apart.
But seriously, I couldn't even attempt to understand the song because it was like five separate audio clips just weakly slapped around each other, and when it's a MUSIC game, the music is a major factor.
