These were my feelings while listening to each one...
I actually do not care for WARNING a whole lot. I don't hate it, but I find that it sounds so familiar...like...I can't think of what it sounds like to me...
I think The GIFT is pretty. XD
Hmm, I really like NO FUTURE a lot so far. It totally sounds like a song that would've suited Love Songs. Wow, it really does sound like "Like a Doll" and a little bit like Friend II.
Out of Control made me think of some of the songs from Party Queen.
And WHOA we really are getting Snowy Kiss part II... XD That HAD to be on purpose, right?! I actually like it though...I like better than Snowy Kiss from what I've heard. It makes me want to dance
And I knew from the other previews that I'd like Story quite a bit. I like her vocals best and the overall progression and feeling it has.
STILL...
...I think Walk will be my favorite song on A ONE. I think overall, this album has a nice amount of energy to me. Even the slower songs aren't a total snooze-fest.
