Isn't that I don't like it. But just 3 pics with nothing special on them except for her holding that... At least on listen!! or no_thank_you the girls have different outfits. I don't mind if you add it when at least 10 pics reference it.
eh, I guess I feel similar when it comes to Vocaloid songs tags, it happens every time someone simply links to a song in comments. A lot of them still have "1 image" attached =_=.
Anyway, if 'Utauyo!! Miracle' can't be a song tag, then how about adding it to the randomness line with K-On! Pencil_Case?
