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
If you’re into fast music you might find certain subgenres of metal are up your alley.
I can tremolo pick 16th notes at about 240bpm on guitar before the wheels start to fall off, so to speak. I’d consider anything over 225 to be fast. Anything crossing 16th notes at 300bpm should just be considered 32nd notes at 150bpm+ IMO. The bars fly by too fast to matter anymore if not.
Honestly I don’t really jive with anything over 300bpm because I feel it loses all sense of groove or vibe-able rhythm. Its fine for little bursts here and there but a whole song at 300+ tends to bore me pretty quick.
