I was about to say the production sounds like shit then I realized it's encoded in 128kbps... I'll wait till I listen to it in better quality before I make a final evaluation but I guess I could post my first impressions for each song:
Genki+ is a pretty nice song. The arrangement gets a little tired halfway through, but it's overall pretty nice. I really like what they did with the intro and outro, and it actually got me a little excited... then it went to the normal song... It's very similar to SEXY BOY...
The singles don't really sound much different from the originals but I seem to like aruiteru more... but it shouldn't have been the 2nd track... it sounded so misplaced after genki+, Egao YES Nude would have been a better choice.
Mirai no Taiyou was nothing special and it didn't really catch my attention, but it felt very old school momusu which I guess was a good thing.
Haru Beautiful Everyday was one of my favorites, but I wasn't really feeling Aika's singing, maybe after her voice matures a little. Eri's singing really reminded me of Aibon though, I loved it.
Sono Deai no Tame ni was an okay song I guess. A little boring and I'm not really a fan of Yossi's singing.
Shanamuni Paradise was a pretty good song, had an avex feel to it. But it really didn't stick for some reason, maybe with more listens.
Takara no Bako was horrible... What did they do to the super cute shit that we loved? -___-
BE Positive was alright and is your average H!P album ender. Aruiteru would have been perfect in this spot I think.
Overall it's an alright album, but it felt really short. I think I like it better than their last 3 albums.
