Best examples of video game sequels reusing music from past installments?

When playing Xenoblade Chronicles 3: Future Redeemed, I was caught off-guard when I made to Yesterdale and the battle music switched from the new one composed for the expansion to the battle music from XC1.

For context, Yesterdale is the area making up and surrounding Colony 9, an area from the first game that now returns in Future Redeemed, which is set decades after and is the last installment of the story arc that began with XC1 and ended with XC3FR (but not the end of the series, as Monolith Soft confirmed). So hearing this battle music one last time really hit hard, knowing that things were finally coming circle and the story being told from XC1 was coming to a close.

So what was the equivalent of this moment for you, when a video game sequel brought back or rearranged music from a past installment and used it in just the right way?
