In which version of Heroes is the music (battle, town, overworld, victory, defeat) the best?

The music in the fifth game is pleasing due to its dynamism and variety, especially for the Sylvan faction; they have a cool drummer. In the third game, there is also a lot of beautiful music, such as for Fortress or Rampart, but the music in the fourth game, specifically the battle and Nature themes, really gets to me (they sing with soul!).
