So just a few minutes ago I had turned on some music on some large speakers in my basement, it was on the tuner so the quality was bad and static sometimes. Well I went to move something around and then my strobe light blinked twice, but it wasn't plugged in, though the cord was dangling by the speakers.
My question is, how is this possible? What exactly happened?

If the strobe wasn't connected to anything (as in, you could have picked it up and carried it away), then you have some sort of electromagnetic pickup from your speaker system. Loud equals lots of current at speaker impedances, so magnetic coupling would be my guess. If the strobes were powered up but their audio connection was unplugged, then you are triggering them with the magnetic pulse from the speakers. Patent it quick.

There is is a good chance that your strobe light has capacitors in it. If so it could be a loose connection that caused them to discharge.
