I know there's one like this in the FFVIII forum, but that applies to just that game. I'm talking any FF game, including Chrono Trigger, Chrono Cross, or whatever Square-Enix game you can think of.

For example, someone could say that, "The Trooper," by Iron Maiden reminds them of Tellah. He's willing to die to take out Golbez. Look up the lyrics, and you'll get it.
