1. First Love = groundbreaking album from a New-York born Jgirl
2. Distance = a more mature First love
3. DEEP RIVER = Revolution in Jpop - Day 1
4. Exodus = Ups and downs, nice effort, a few gems
5. ULTRA BLUE = sophisticated in a good way, her second best
6. HEART STATION = golden hits in there
7. This Is The One = Merry Xmas Mr Lawrence
8. Single Collection Vol. 2 (disc 2) = showed us love, thanks

I describe her albums as... mellow and soft yet vibrant and tough, fast yet slow, heart warming yet heart breaking, something that gives the feeling of falling in love yet it also gives something about falling out of love, being truly happy yet sad at the same time, making you cry yet making you smile as well... in other words "being human"

Precious - doesn'tshow her talent too much, but I'm impressed she was able to do album at that age.
First love - I don't like most of songs. She couldn't pick singles better, "Automatic", "First Love" and "Movin' on Without You" are really the best.
Distance - Hikki has improved her style, nice album with pop/rock songs.
Deep River - experimental, seems like she finally wrote songs in the way she wanted too
Exodus - well, some songs are perfect (Kremlin Dusk, Animato), but some are awful.
Ultra Blue - beautiful ballads mixed with more up-beat songs (This is Love, Keep Tryin'). Still experimental, but not as much as Deep River.
Heart Station - the most emotional album, and the most personal, I guess.
This is the One - Utada tries to go mainstream. A way different from her japanese work, however, it's still better than lots of dance music we can hear on the radio or tv.
