2003 J-Pop Hit Songs Special: The Golden Era of Music When Diversity Flourished (21–30)
JEWEl SONG / BESIDE YOUBoA
A slow-tempo song.
It also became the theme song for the drama “All About Eve.” She’s Korean, but her Japanese pronunciation is very clear.
Her beautiful yet powerful singing voice is captivating.
When she debuted, she was active only in Korea, but she made her Japan debut the following year and is said to have been a pioneer of the K-POP boom in Japan in the 2000s.
IT’S SHOWTIMEB’z
B’z’s 34th single, which topped the Oricon weekly and monthly charts and ranked 12th for the year.
It’s a characteristically fiery B’z track that was used as a tie-in for three sports-related TV programs.
The song is built solely from guitarist Matsumoto’s “commonly used minor-key chords,” and it reflects his playful spirit—he’s said that “the fun of music lies in the limitless possibilities within a limited scale.”
morrowDragon Ash
Released after a break of more than a year since the smash-hit previous single “FANTASISTA,” this work isn’t an upbeat, high-energy track but rather a downer-style song built on two chords.
Kenji Furuya, the vocalist, reportedly said in a magazine interview, “If I could take one Dragon Ash song with me into my next life, I’d take this one.”
Choo Choo TRAINEXILE
Now a familiar upbeat tune loved across generations, this is one of EXILE’s signature songs and a famous cover of the original by ZOO.
Thanks to the success of this track, they rose to the level of performing on the Kōhaku Uta Gassen (NHK’s year-end music special).
BEAUTIFUL DREAMER / STREET LIFEGLAY
A track with strings in the background.
It’s refreshing, upbeat, and easy to groove to.
The pop feel pairs perfectly with vocalist TERU’s powerful high-tone voice, and I imagine many GLAY fans love this song.
