Alternator?

[ohhh my]

If the alternator was running efficiently i should have never lost any electrical power which is why i think it's the alternator. matter of fact, you should be able to remove the battery from a running car and it should still run if the alternator is good.

Never do this to a modern car.

Not always, you should have shut off the stereo at the first sign of trouble to reduce the pull on the battery and save power for the crucial headlights. If the battery itself is dying, it could cause the scenario you experienced but of course it could be the alternator as well.

How is your key in the ignition switch? Does it turn OK and do you hear a clunk noise when you pull the key out? There is a possibility that the ignition switch failed.
Like wvboxst3r said, you should have been able to drive for a ways just on the battery alone, even if the alternator failed.
