no songs quite unite people quite like What Makes You Beautiful by One Direction and Never Gonna Give You Up by Rick Astley
the happy birthday song is also on that list except when my family sings it, it sounds like a demonic anthem or something CUZ PEOPLE CAN'T SING IN THE SAME KEY UGHHHHH
my favorite way to sing happy birthday is to only sing the word birthday and nothing else but keep the timing and notes the exact same, itβs incredible
that's very valid and actually a good challenge, might try it next time it's someone's bday l
