Yup, I've been listening to their singles lately and I find most of (if not all) their songs fun and addictive for some reason. Maybe it's because they're somewhat uplifting? Well, that is if you understand the Jap language or, as what I did, read the translations~ XD
For those who don't know Buono!, go ahead and 'google' em. Their basically a Hello! Project unit consisting of Hello! Project Kids Momoko Tsugunaga (the cute-perky-energetic one of the group) and Miyabi Natsuyaki (the mature, pretty one) from 'Berryz Kobo' and Airi Suzuki (the demure one with the voice - not that the other two have bad vocals or anything) from sister group 'C-ute'.
My opinion is, these three sound great together.
Buono!'s songs so far are pretty much all catchy and dance-worthy by my book. I guess I also like the 'cute' image they portray most of the time; culture so common amongst Japanese (female) youths. How do I know this? For one, I've been there, Japan that is. Try it yourself!
Childish? Perhaps a little, but hey, maybe that's why it's so fun.
Here's their most recent (5th) single to date, 'Rottara Rottara'. Yeah, the song name doesn't make much sense and it's probably not their best single ever, nor is it my favorite one, but I like it all the same (and have been brainwashing myself with it since Rixie-chan showed it to me weeks back).
And before I leave, just for clarification purposes:
Yellow = Airi ----- Pink = Momoko ----- Blue = Miyabi
Enjoy!! XD
