Is Three Kingdom worth buying

I’m looking to buy three kingdoms and I have a few questions:

1. Is the soundtracks mandatory to buy cuz rn every other dlc is on sale except the two soundtracks but if I don’t buy it, am I not going to get any music in game?

2. I’m huge on playing warhammer series and I rlly liked one of the character creation mod (shoutout to that modder 🙌) and I’m hoping if there’s also one for three kingdoms but most of the mods are in mandarin and it’s hard to translate.

3. What dlc do yall recommend the most and what are some mods that are must have?
