It makes me very sad that somebody would think the H!P Kids covering 3nin Matsuri is better than the original. :( Rika, Kago, and Ayaya are such a cute combination, and I'm not even that big of a fan of any of them, haha.
'Aoi Sportscar No Otoko' and 'Kiiroi Osora De BOOM BOOM BOOM' are the best summer shuffle songs, closely followed by the '03 summer shuffles :3 'Summer Reggae! Rainbow' is the best 2001 summer shuffle song. Also, Yurina's, Miya's and Chinami's version of 'Chu! Natsu Party' > 3nin Matsuri's version.
