For me HEART STATION is better. It has only one song I don't like but ULTA BLUE has two songs I don't like. Although the olter songs on both albums are amazing. Actually, I think HEART STATION is my favorite album from Hikki, with This Is The One of course. But ULTRA BLUE has my favorite song, Passion...

...this is so hard. XD Anyways, I say HEART STATION.

ugh this's difficult because I like both of them

but I go with ULTRA BLUE because that was 1 of the 1st few jpop albums that I listened to when I started my jpop music journey 3 years ago

I love both! but I think Ultra Blue is the better out of the two.

Neither! Hikki didn't bring it like she did with her first 3 albums!

Ultra Blue. Heart Station is a very generic/average album. There's nothing special about it, except for a couple of singles. Ulltra Blue is a diverse and complex album :yes (and more melodic)

Heart Station.

I pick Heart Station because even after I played it what seems like a billion times and had to take a break from it when the break was over I still loved it.

The tracks flow together very well.

Ultra Blue is nice too but I'll have to go with Heart Station.

Heart station ^^ .

HEART STATION hands down imo. I like ULTRA BLUE but I really prefer HEART STATION more. <3

Ultra Blue is <3

A perfect blend of sounds.

ULTRA BLUE is better. Although HS has Flavour of Life, which is my fav. song from Hikki.

HEART STATION

ULTRA BLUE, but I LOVE HEART STATION TOO!
What made me pick UB was because I only like HEART STATION, Nijiro Basu, Teku 5, and Prisoner of Love. I enjoyed more songs on UB. HS will always have a place in my heart since I was in Japan the time of it's release :)

ULTRA BLUE, but I love HEART STATION too :)

ULTRA BLUE
