Spotifies come and Spotifies go, but that folder of badly-sorted MP3s will still be there in the 2050s.

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.
