When Myspace went under, so did all the songs uploaded to the platform. The people behind the foreclosure didn't exactly leave the userbase enough to pack their belongings, so down went over 50 million song submissions, many of which were likely associated with the strong emo undercurrent that was everything back in 2006, if you recall.
Turns out, after 10 years of deep hibernation, someone over at "the Internet Archive" decided they would try and excavate as many of the lost Myspace relics as possible, because as you know: not everything you delete function gets erased from the unconscious layer of the deep web. Before we get into the relief effort itself, it might be worth explaining what purpose "the Internet Archive" serves the public domain by offering up over 351 billion postdated web pages on consignment.
Just as Myspace was going under, it issued a statement basically claiming the 50 million song submissions were lost due to an unforced accident. Of the millions of files reported missing, the archival project was able to revive nearly half-a-million of them. A data analyst that goes by @pinkpushpop on Twitter was able to locate a good number of them by diving into the proto-beginnings of video upload technology: among them, early clips posted by Katy Perry, Nicki Minaj, and a very green Donald Glover. A thorough account of the excavation efforts can be viewed over at Hobbit.
