Dubbed the “Queen of K-POP,” BoA burst onto the Japanese music scene like a comet in the early 2000s.

The single she released in Japan in August 2002 is a dance track distinguished by passionate Latin rhythms, which shocked music fans at the time.

The lyrics convey a will to believe firmly in oneself, to carve out the future as if in battle, and a fervent determination to stay true to love no matter the difficulties.

The album bearing this song’s title, VALENTI, was released in January 2003, debuting at No.

1 on the Oricon Weekly Albums Chart and achieving million-seller status.

It was also widely loved as the theme for the PS2 game PROJECT MINERVA and the music program JAPAN COUNTDOWN.

Yūshinron, RADWIMPS’s fourth major-label single, is one of their early signature songs and a beloved classic among fans.

Some people now in their 30s may have first discovered the band—who were then rising as a cutting-edge young act—through this track.

The song is memorable for its catchy chorus and lyrics with a distinctive worldview, but the part to watch out for when singing it at karaoke is the fast, rap-like delivery.

Practice to keep your rhythm steady, and try to avoid sounding too flat or mechanical as you sing.
