I play rhythm games a lot and accidentally developed a taste for hardcore/speedcore music, which is probably uncommon. So this is something I’m quite curious
I think my cutoff for considering something fast is like between 200-220 BPM. For example, xi - FREEDOM DiVE has a BPM of 222.22, which… apparently I only consider as “fast”. Too fast is like 300 BPM for me
I agree with 220 gabber / hardstyle type stuff being my upper limit, beyond that I think it is just getting a bit too fast and messy.
Even saying that I have to be in the right mood for that speed, the right mood usually being rolling my tits off somewhere.
DnB is the sweet spot for more everyday, listenable speed being more in the upper 180s usually IMO.
