The metadata fields does not work like this.
In this mapset, I believe that the metadata is set like this :
Artist : Official HIGE DANdism
Title : Cry Baby (TV Size)
Source : 東京卍リベンジャーズ
Tags : tokyo revengers short version
Letters are case sensitive for this section.
There are quite some amount of unused files, namely
"normal-hitclap23.wav"
"normal-hitfinish23.wav"
"normal-hitnormal23.wav"
"normal-hitwhistle25.wav"
"soft-hitnormal.wav"
"soft-sliderslide.wav"
They take up unnecessary spaces which increases the download time of the beatmap.
The difficulty naming does not work like this.
"Not really hard" -> Hard
"Hard" -> Insane
"Nor really insane" -> Expert
"Insane" -> Extra/Extreme
That is conventional difficulty naming, your naming method is never seen on ranked maps.
