Okay,
Love Paradox is basically the styles I love from Namie and Kuu, so it's nice to hear her try her hand at it. I just think her voice has a hard time competing with the music? Maybe it's my speakers, though XD Idk it just didn't seem like I could hear her clearly at a few parts. I still love the song though. It's fun.
As for
Under the Same Sky -

THIS is what I mean when she should do soft songs!! Her voice doesn't sound as strained here, nor does it seem like she's competing with the music throughout the song to be heard. It's such a lovely song... It sounds soooo gorgeous and relaxing. Man, I think I like this even more than Love Paradox D:
Vanilla: Okay this is the kind of pop I usually avoid lolol. It's just not my thing but I'll persevere. It's sugary and... well, idk. I'm not really liking it all that much

I guess it's because it's one of those summer-y releases and they're supposed to be upbeat, yay~ awesome summer songs, and that usually runs opposite to my tastes. Vocally though I think she sounds good, just not very lively. Like I've said before, I think soft pop songs and ballads are Leah's best way to make herself a hit: they fit her range so well and she just gets a little lost in more poppy and upbeat tracks, IMHO.
LOVE SWEET CANDY: Seems like a cross between Love Paradox and Vanilla D: Interesting, interesting... The title is a little misleading lol. I was expecting Vanilla to sound more like this and LSC to be a little more sugary. It's good, I guess. It doesn't really hold my attention too much, though - it's acceptable but there's really not much to it, you know? Formulaic.
