The log file was included in the album, so it has to be Taishi/Electro.muster who made it. Also the log file were the best source I found to get the metadata as the other sources doesn't give much info about the actual song metadata
And for the > Filename D:\Музыка\VOCALOID\Electro.muster & WOM feat. 蒼姫ラピス - A Sugar Business\Electro.muster & WOM - A Sugar Business.wav
I think the part after "VOCALOID" is the song metadata, and the next part after the \ is the album name, or perhaps it's the opposite (?)
But yeah, I think this is a tricky one...
