EDIT: Seems dynamic music is back in style in some very recent games, many of which I haven’t really played yet. Good. 
For me, it’s dynamic music, the kind that some games had that adjusted moment by moment to what was happening in the game.
The best-known example of this in the 90s game TIE Fighter, where the moment more enemy (or allied) ships showed up the music would have a little additional flourish to acknowledge the shift in battle. There were pre-battle tension tracks, battle music, complications of battle, grandiose flourishes for the arrival of enemy or even allied capital ships, and victory and failure music all ready to flow into the next seconds of the game.
A lesser-known but still excellent example of this was in Ultima Underworld and its sequel, where drawing a weapon had its own special “preparing for battle” tension music, getting attacked had a jump-out-of-your-skin joltingly sudden musical start that actually scared me as a kid when I got ambushed, music for battles going well, going poorly, victory and defeat.
I wish more games did those sort of second by second musical changes, but they’ve sort of fallen out of fashion for the most part. 
tbh I think we should both get a life
Not buying into the eleventh hour scorched earth tactic here.
You came to demand that other people play your games in a way that has a history of making them miserable and unhappy and even quit those games. If you don’t get your way, you don’t get a personal benefit. If you get your way, other people that are (presumably) not you get a blank check all over again to be assholes to those players.
This is one time where the status quo really is better for people that you ignore and possibly look down upon. Spare me the “get a life” gambit, or just consign yourself to it.
ok
