Do all Trackers play a little song?

I bought a nice little '93 Tracker for my wife.

She loves that vehicle!

When she turns it off, after about 3 seconds, the dashboard
plays a little tune......

Is that normal !?

What is it all about?

BTW - WHAT is the actual Geo name for that color!? Ha!

does she have an aftermarket cd player or alarm in it? because thats more than likely the case as far as the tune goes.. my sony cd player in my camaro does similar, goes through a beeping sequence while shutting down after turned off.
