I tend to prefer the latter seasons over the earlier ones, but something I REALLY miss that they used a lot more in the earlier seasons was the 'Warrior Princess' theme. It was used perfectly in S3 One Against An Army, and and it was there in S4 Endgame with Xena knocking out some Romans. I had pretty much given up hope on hearing it again, but they finally used it again in S5 'Little Problems' with little Daphne warning those goons to save themself the embarrassment and then kicking all of their asses. Can't remember if they used it at all in Season 6?

The usual Xena theme music is awesome, but there's something about the warrior princess one that just gets you super energized cause you know some major ass-kicking is about to go down!!
