More than 25 years.

The first thing that it played to me was Crockett's Theme.

I spent the first few seconds looking at the description, which said something else, and saying to myself "No, that's definitely Crockett's Theme.".

Haha, nice. I searched and there’s one keygen that also played Crockett’s Theme, but at least it credited it. Then another one I shuffled to was the theme from Airwolf.

These are pretty much staples for any synthesizer music collection that ever was. There's going to be an Axel F in there somewhere, too. And possibly Chariots of Fire.

I was amused that Crockett's Theme was the very first one played to me. Alas, I didn't note the sompletely unrelated title before closing the page, and have no clue now where it is in the collection.
