Hi everyone! I realize I've been using category tags inconsistently, so I'd appreciate everyone's input on the following three points about what category tags to use and when.
Currently this is how I think of it:
1) [[Category:Group Name]]
When to use: any time a group sings in a song.
Example: Hyokkori Hyoutanjima has the tag [[Category: Kobushi Factory]], [[Category:Tsubaki Factory]].
-For groups that have gone through name changes, should both names be tagged?
Example: does Sukichan need the [[Category:ANGERME]] and [[Category:S/mileage]] tag, or just one?
-For groups in established "supergroups", should their individual group names be tagged?
Example: does Chou HAPPY Song need the tag [[Category:Berryz Koubou]] and [[Category:C-ute]] besides the tag [[Category:BeriKyuu]]?
2) [[Category:Group Name Single A-sides]] / [[Category: Group Name Album Songs]]
When to use: description of the first release a song has had, under that group's name or former name.
Example: LOVE Machine has been on 4 albums but it was first released as a single, so it only has the tag [[Category: Morning Musume Single A-sides]]. Aa!'s Yume to Genjitsu was released on a Petit Best Album so it gets a [[Category:Aa!]] tag but no release tag, since [[Category: Aa! Album Songs]] would incorrectly imply it came from a (nonexistent) Aa! album.
-This is extremely rare, but for A-sides rereleased on separate singles should both releases be tagged?
Example: does Ai no Tane need the [[Category: Morning Musume Single B-sides]] as well?
-Do digital singles count as a first release?
Example: Would Hana ga Saku Taiyou Abite and Gosenfu no Tasuki need the [[Category:Morning Musume Album Song]] in addition to [[Category:Morning Musume Single A-sides]]?
3) [[Category:Unit Songs]]
When to use: as mentioned in the lyrics template description, this is any song issued on a group release that is not sung by the full group. This technically describes member solos like Tsuugaku Vector as well, but I've been tagging those as [[Category:Solo Songs]].
-Do solos fit under the "unit songs" description or is it implied to be units with two or more members?
If anyone's seen me use any other category tags incorrectly or has any other points to clarify, please let me know!
