mass update producer_(idolmaster) -> producer
mass update producer_(idolmaster_cinderella_girls_anime) -> producer_(cinderella_girls_anime)
The series has been around for over 10 years and I can't think of a more relevant use of the term on this site.
There is exactly one non-idolmaster, vocaloid image (post #2679650) on the site that uses the generic version of the tag, and as far as I can tell, both characters in the image are accounted for by other tags. There apparently is a producer character used by some vocaloid fans, but it's so minor that this the only image to reference it. It is also likely that this character is only called producer due to the popularity of idolmaster and its use of the term. The remaining producer images are all tagged that way because it's implicated by producer_(cosplay) instead of producer_(idolmaster) for some reason.
There are a number of other derivative producer tags that haven't been listed as they can easily be done manually. producer_(idolmaster_anime) is excluded to avoid confusion with other the anime producer tags.
