I was talking to Jess on MSN, and an epiphany was had. Why isn't it Lightning magic? That's what actually hits the enemy: lightning. In a few games it's Bolt or something, but it's mainly Thunder. Thunder is sound. Maybe it was because Thundaga and such sounded better; you'd think they'd be accurate though.
It's like this in KH too.
