not sure where you get the .mp3 from but the audio quality looks compressed poorly and some versions got different bpm, which is why it's hard to improve it.
actually, please just actually use the one from the ranked / qualified version since yours is unrankable anyways regardless of the bpm

according to rc, you shouldn’t rank overencoded audio, since there's been going on a lot of valid disqualifications due to quality improvements
because the audio cut offs around 16khz, which is similar to 128kbps while this is encoded 192kbps, while you're looking for 18-19khz
I can provide you a 179.94bpm ver but you would need to do resnappings or take the qualified/ranked 178bpm ver., but your decision
Metadata:
岡本 信彦 should be together (岡本信彦) for searchability.
sinyus20 is optional, but since it's been used for previous sets, better ask Take on this.
Your_Stary shouldn't have underscores as it affects searchability but this instead -> Your Stary
some difficulties also have inconsistent tags, so take care :3c
Hitsounds:
soft-hitclap.wav, being used as a snare, sounds like a whistle and go under the song too much, which isn't sufficient hit-feedback as a custom sample enough.
00:48:002 - 00:52:174 - 00:56:680 - missing kicks
00:47:919 - 01:17:457 - whistles for additive feedback (Your Stary's Insane)
00:06:282 (5) - 00:13:791 (5) - 00:21:635 - 00:21:551 - 00:21:802 - 00:27:643 - 00:52:174 (3) - 01:22:380 - whistles for all diffs
some vocals like 00:02:277 (1) - 00:02:944 (2) - 00:04:780 (2) - aren't whistled.
Also chnage the hitclap to a kick as it doesn't reflect sounds in the song rn
