create implication holiday_holiday_(tenko)_(love_live!) -> holiday_holiday_(love_live!)
I've been treating this song tag as an umbrella tag, the subtag is for stuff from the yt short. Now, I don't know if what I'm doing here is correct, but if it is, here's the implication. If people don't want to see stuff from the subtag, they could just negate it (holiday_holiday_(love_live!) -holiday_holiday_(tenko)_(love_live!)), but now 1/3 of the main tag is about this short.
I put this in a separate topic so it doesn't get buried with the run-of-the-mill implications.
