I was just thinking "I need to burn some music CDs for when I travel", just in case.

I went on a car trip earlier this year, but forgot my bluetooth to aux adapter. I tried to buy one while I was on the road, but places were sold out, didn't carry them, or they only sold them via online orders.

As luck would have it, I still had some old CDs I'd burned 20ish years ago sitting in my glove compartment! I honestly did not expect them to work because they'd likely spent at least the last decade+ in that glove compartment, enduring extremes of heat and cold. They were scratched to hell and back and I had always heard that they degrade and become unreadable after a certain amount of time, even under ideal storage conditions.

Luckily for me, though, they mostly worked. I think there were a couple of songs on one disc that skipped a bunch, and everything else played fine. I rediscovered a few great songs from my youth that I'd not heard in so long that I'd practically forgotten about them.
