They can't make the results into a BEST album, since all of her songs are eligible for voting, and she's certainly not including anything pre-ABEST2 in a new best album.
However, I do have a feeling Mu-mo might make a sort of unofficial best album, considering they're coming up with a "surprise" or something. I hope not, though
I would kill for A BEST 3, but not for some TA-members-voted best.
