in philosophers stone, it says that the school song is sung in any tune the person wishes but think of all the possibilities?? what song would snape have chosen? what did baby tom riddle sing? did a muggleborn ever throw some beyonce or nicki minaj in there?

Many purebloods and halfbloods wondered why a large group of muggleborns always got detentions despite being good at school. After many hours of eavesdropping and visits to the hospital wing, turns out they were in trouble for bringing a muggle item called ‘Netflix’ into the castle and were catching up on muggle shows throughout the day. The purebloods found out they were in strange groups called fandoms and obsessed over boats and 'oteepees’. They even had a special group called WiFi and always changed the WiFi group password to stop any other wizards from finding out.
