Buono!’s debut single stands out with powerful guitar rock that goes beyond the bounds of “idol” music.

Released in October 2007, it was used as the ending theme for the anime Shugo Chara!.

It debuted at No.

This track delivers a straightforward portrayal of the struggles and hopes of teens searching for their true selves, set to a fast-paced, exhilarating band sound.

When you’re ready to start something new, the trio’s strong vocals give you courage—an anthem-like number that cheers you on.

GOOD DAYSZONE

Although ZONE is strongly associated with being a girls’ band, they actually started their careers as a dance group.

This was their major-label debut single, released in February 2001.

The members reportedly felt some internal conflict as they launched into a new style called “bandol,” performing while holding instruments.

Yet this track turned out to be such a bright, hopeful rock tune that you’d never guess at that backstory.

Its positive message—that as long as you have your friends, you’ll be okay—gently gives listeners a reassuring push forward.
