I've only heard Queen of Hip-Pop, PLAY and PAST<FUTURE
Queen of Hip-Pop - I hate this album, with the exception of WANT ME, WANT ME, which is just too much fun to resist. The rest is either fairly average (the title track, WoWa, No (part 1), or just plain terrible (the rest of the album)
PLAY - So-so. Hide & Seek and Full Moon are brilliant. Top Secret, Violet Sauce and Baby Don't Cry are pretty good and I quite like the craziness of It's all about you. The rest is forgettable.
P<F - My favourite
! That being said, I can only bare to listen to 1/2 of the album, but what a ridiculously cool 6 tracks it is! FAST CAR, COPY THAT, LOVE GAME, WILD, Dr. and Defend Love are all awesome. The rest ranges from uninspiring to a complete mess (FIRST TIMER must be one of the worst songs in the history of music.)
Damn, I feel like a bad Namie fan now...
