Some people liked to listen to music...for fun.

Some of you, little procrastinators, listened to music while writing the ten-million assignments you ignored in the last day. Some listened while reading, some while writing, drawing, some of you are just very good performers!

And then there was Childe... Who listened to Rasputin while commiting arson, murder, theft and whatnot. Also, it was a personalized version.
