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.
I just found all my old burned CDs including the folder of them I made for my spouse. I can’t believe those songs won her over lol, but 20 years later here we are.
