Theatre Etiquette
Tina was the worst! I get that the songs are all very well known but there were gaggles of women progressively singing louder than each other to prove that they are grooving the hardest. It's also particularly bad when its the beginning of a song like Lets Stay Together where the live staging has some acting mixed in (because its a broadway show and not radio version of songs) so they start singing ahead of the acting.
