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 actually got rid of all my old MP3s years ago. Not because I regret acquiring them, but because the quality sucked. Even 320kbps. You can’t tell CD from MP3 through my stereo, or in the car. But it is really obvious through my headphones, and ruins my critical listening experience. Had to re-rip all of my CDs to lossless, and lost all the ones I didn’t have CDs for.
