Here's the direct link where you can see all the O-dio videos

the quality of the music in this last video is so bad and the bass sounds horrible in my headphone.
You mean the hololive one? Well... it's phonk music. I'm not sure if it's your headphones or not, but phonk tends to sound like that on purpose. It seems like a new generation of people grew up with the ironic "bass-boosted" memes and ended up unironically enjoying that kind of stuff so now we got a new style of phonk.

and that kind of "purposefully choppy" quality existed in those old songs back too, though it wasn't as ridiculously bass-boosted as the new phonk songs of today.
