All diffs except inner
I dont think alternating between 50% and 70% is a good way represent volume changes in music. Especially stuff like 00:58:497 in between kiais is just too quiet
Imo stuff like 00:15:640 onwards is 60%
00:46:354 50%
00:53:616 add 70% line
00:58:497 60%
01:06:116 60%
01:24:211 60%
01:39:687 50%
01:46:949 add 70% line
01:51:830 60%
01:59:449 60%
02:17:544 60%
Kantan is different but the general idea is the same, avoid 50% in between kiais and also only use 50% in the quietest part
