Really Good
I love these songs!
I've always liked Yamapi and Kamenashi to begin with, but I think these are really great songs. Nobuta wo Produce was such a great drama too, and Seishun Amigo really fit as the ending song for the show. Yamapi's song Colorful is the ending song for another good drama called DragonZakura (which Yamapi is in). Kizuna is the song played all throughout Gokusen 2 (which Kamenashi is in). I really love these songs and dramas! x]

Soooooo Gooooood
I live in Japan and I'm the typical teen, have to watch this show "Nobuta wo Produce" In other words "Producing Nobuta" which is a great drama that children and adults watch. Sadly it ended last night.
Anyway this song is sang by the 2 main characters who are actually from Japanese teen bands. The song is played as the ending theme of the show and made a hit release, giving these stars the credits they deserve. Although on the radio you will only hear the 1st part, as the 2nd part is VERY difficult to sing, especially for foreigners like me!!!!!
But it's a great song, great music, and soooo coooool!!!!!
