It is good when you do a thing in the game and a little music plays. This is why Zelda is popular. If Dirt Rally played a jingle when I got a turn just right I'd be a happier person. Unless I still never heard the jingle I guess

It is good when a boss from early in the game shows up late in the game as a regular enemy
Not even "late", start using him as a regular grunt straight away in the next level.
It's good when the animation gets slightly sped up or slowed down so that hits land on beat with the background music.
