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.
