Ooh…I have an entire playlist of my favorite OSTs. Long term, I’d have to say One-Winged Angel, specifically the remake. Also worth mentioning:

Dark Soul 3 main theme

Feel from Lies of P

Dependent Weakling from Nier, specifically this version: https://www.youtube.com/watch?v=ePXlfGufSjk&t=0

Agree. For example, Tunak Tunak Tun. Love it, don’t understand a word. 😁

If you are in a noisy environment, you can use earplugs with your bone conduction headphones. That’s what I do on the treadmill and while mowing the grass.
