well put on what you said Cat
like what Meat Pao / Travis has mentioned , LOVE is BEST is maybe a last ditch effort on avex's part to revive her flagging popularity in which I seriously doubt that can happen at all
if only she included Kingyo Hanabi , Planetarium , Cherish , Kurage Nagareboshi , the tracklist would have been more interesting but
& actually , Ticket & drop. are B-sides songs found in Pocket & Planetarium
