Generalmp3 with 96kbps is unrankable atm.try to find with 128kbps as example.
Capitilize "s" in title, " Musouka (TV
Size) ".
Make name of topic like your artist/title in game.
Audio file without name? D: " .mp3" is working, but... oh, nevermind.
Set audio lead-in 0.5 or 1 sec in all diffs, because player has ~2 sec.
White color is not recommended, but okay.
One of your diffs must have less than 3 stars. I guess you could make your normal a bit easier.
Make end of kiai time in all diffs at 01:20:646.
Add "ending" or "opening" (I don't know what is it) to the tags in all diffs.
Your offset looks a bit off, it must be 1846 (yours +15ms). Change it in all diffs + resnap all notes
InsaneHP -1 (too high)
00:04:527 (7) - remove note
Use claps constantly, at this moment, claps sounds randomly and weird.
ClapsFinishes are usually placed at high white ticks.
00:39:229 (x) - add note
00:48:967 (4) - remove note
00:49:079 (5) - imo, must be :
01:18:408 (2) - add whistle to the end
01:23:221 (5,6) - remove 2 notes
HardAR -1 (too high, like in Insane), OD +1 (too low)
Claps suggestion, like in Insane
NormalOD +3 , AR +4 , because AR 0 and OD 0 used never, especially in Normals
check AImod, you have some distance problems + make this diff easier (under 3 stars). Or add Easy.
