I have a folder of MP3s, some of which date back to 1999, just a few years after the format was popularised. Most of them have utterly terrible names (think RIDEONAM.MP3). I think at this point they might even survive the heat death of the universe. And they’ll still be terribly-organised.
Unfortunately, the fish aren’t as plentyful as they were back in the good ol’ days but I’m still finding most of what I want on pirate bay or 1337X. It’s just a case of finding the option with the most reliable seeds.
