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
Anything above 180 is fast in my opinion, but my favourite is somewhere around 140 or 280. Among the non-weird ones, I don’t think I encountered “too fast for me” musics.
