One thing about AKB48 singles be it the main or coupling tracks, it`s hard not to find members who auditioned for Morning Musume, some as recent as 8th generation as this video has some, like all of their videos.
I sometimes wonder what if those members had joined Morning Musume instead of selecting Miracle Musume would things have turned out the same.
