As far as I know, the last discussion on this topic was four years ago, and it didn't seem like there was a consensus.
There seems to be some inconsistency with the titles for the Touhou Project tags. Most works use the subtitles while a select few use the main title, which seems inconsistent with how danbooru usually handles these (like Mahou Shoujo Madoka Magica). There seem to be a few copyright tags which uses the subtitles, but these were for copyrights in which the English subtitle is a translation of the original title, which isn't the same with the Touhou Project works.
Additionaly, I'd like to request a alias of "touhou" to "touhou_project", as this is the series' full, proper name.
And last, the music cd's should inplicate "zun's_music_collection", as this is the title of the cd series. I'm not sure if I should add the implication to the new proposed names or the old ones, so I left it out for now.
