I have to say that I really liked a lot of the music from the cartoon series.  There was some nice ethereal themes that took me back a little bit to the first half of the first season in mood, and the action music was pretty decent.  I honestly liked the music overall in TAS better than most of the music from the 3rd season of the live series, where they seem to have abandoned the absolutely great themes (for the most part) from the first and 2nd seasons.
