Oh music in RPGs. I love you, I really do. I'm a big user of rythemn bot for discord games... but at the same time I am someone who as been frustrated by GMs spending ages finding a song they want mid game.

I love a good soundtrack set to a scene, though I have a tendency to get caught up in the moment and either forget about the best song for the moment or think of it afterwards.

You can never go wrong with Yackety Sax. If the players are rolling dice, shenanigans will ensue.

Unfortunately, I can't think of a good counterexample. In my longest-running campaign, we had a fight with two youngish kraken that literally was "We sail away from them and fire the deck mangonel at them. They chase us. We sail away and fire again. The wind changes. We tack and repeat." until we won. My other campaign - fight with two Devourers at level 3. We ran away while hitting them until they died. Goblin fight? We ran around while they kept running onto the battlefield to be slaughtered. The only reason I can think of for why it wouldn't work is because our combats tend to last over an hour, and you just can't listen to Yackety Sax for that long without receiving significant psychic damage and possibly a WIS penalty.

I roll to ensue

My thought for this scene was immediately "Break the Sword of Justice" from Tsubasa: Reservoir Chronicle. Because it involves the story's badass swordsman standing on a tall roof while laughing menacingly and declaring his attackers weak.
