 Did you know that MySpace lost all of its content before 2016? Due to a faulty server migration, every photo, song, and video that was uploaded to this one popular social network, all of it was accidentally deleted. That accounts for 50 million songs from 14 million artists like Lily Allen and Arctic Monkeys. Of course, many of these have backups that are probably on Spotify by now, but those that didn't are now lost forever.
