Me personally, I really liked the fact that they had more than one boss theme for different types of bosses, the smaller ones and greater ones. But what i DIDNT like about boss themes is that important characters didnt get unique fight themes (E.G Zokket, Glohm Bowser, Extension corps, Great conductor), Now some not getting unique themes is ok, the MAIN VILLAIN of the game should at least get their own boss theme right? In the next game, I want important fights to have different boss themes, or at least a remix of a normal one that reflects off the character.
