Why do OE radios stop working?

[87BlazeLS]

Good luck on your hunt. As the masses are going to more modern forms of listening enjoyment
those of you that wish to stay in the 80's have to pay the price to keep that era going when it comes
to listening to music. It would be much easier to just go with a Cd player. Your call.

I am more amazed that anyone still has functioning cassettes, I can't remember the last time I had even seen a cassette.
I still have a brand new Ford 2003 double din cassette radio and I could not even sell it for $15 on Craigslist.
