voted for the ff: (solely based on the main tracks and the PVs)
Berryz Kobo - Dakishimete dakishimete - this song gives Berryz some attitude. Their costumes they used were awesome, definitely better than watching them dance in monkey suits. C-ute pwned them in costumes last year.
Erina Mano - Hajimete no Keiken - being repetitive keeps it stuck in your mind.
Buono! - MY BOY - they had a bit of difficulty with the song being fast-paced but it's definitely one of Buono!'s best.
Morning Musume - Nanchatte Renai - I only started to like this recently but I never loved a Morning Musume song like this since Sexy Boy
S/mileage - Suki-chan - I like this better than their 2 previous releases. Although good, I felt that their earlier songs were too slow/mellow for a young group that's supposed to be full of energy and Suki-chan changed that. Still can't find the PV for this though.
The C-ute singles are good but the ones they had last year were slightly better.
