Huge upgrade from Drum 'n' Fun with all the different game modes, in-game shop for the points you collect as you play, achievements, funky story mode and a Battle Pass-like progression bar that unlocks you even more stuff.

Music Pass was a little questionable at first, but 500+ songs right after unlocking and 8 or so new ones every month look good enough for the price. Now if they add Joubutsu 2000 that would be priceless!
