Oh god. To refrain from stanning too much, I'll just pick top 3
1. UNIVERSE - To me, this has some of her best album tracks (Step Into My World, No Way, You're So Beautiful, Comes Up, SUPERSTAR, UNIVERSE) and ECSTASY, Can We Go Back♥♥
2. JAPONESQUE - Same as above. I think in the long run it will end up beating UNIVERSE, it's just the latter has a lot more memories to go with it for now. Best songs: V.I.P, BB Boys, So Nice, ESCALATE, Lay Down, No Man's Land, Slow♥ - oh and some of them have awesome PVs.
3. TRICK - Hated by so many people but I really really loved it for ages, it was my favourite before the other two kicked it down
Honorable mentions: secret, second session, Dejavu, Kingdom & ETERNITY.
