BUR #42433 has been approved by @nonamethanks.
rename taishou_roman -> taishou_roman_(yoasobi)
rename chiyoko_(taishou_roman) -> chiyoko_(taishou_roman_(yoasobi))
Due to its ambiguous name, Taishou Roman, a tag intended for a specific Yoasobi song, ended up being mistagged with posts that were generally referencing the Taishou era, so I think renaming it is necessary. The chartag associated with the song will have to get a slightly uglier qualifier as a result though.
