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’m a total Speed Queen I love high BPM songs in rhythm games. I agree with your take, I consider anything from 200-250BPM a fast song. 300 BPM is insane speed, I played Yaminabe!!! on Project Sekai ages ago and it briefly reaches that speed at the end and I struggled with that. I have no idea how people play the expert and master chart of that song.
