Anime songs that were hits in the 2000s: A nostalgic collection of legendary tracks (61–70)
DAYBREAK’S BELLL’Arc〜en〜Ciel

With its grand melody and profound message, this song is a gem of rock that leaves a deep impression on listeners.
It masterfully fuses L’Arc~en~Ciel’s distinctive sound with lyrics themed around anti-war sentiment and love for humanity.
The intricate drum and guitar rhythm patterns, along with a youthful arrangement reminiscent of their indie days, are also striking.
Released in October 2007, the track was chosen as the opening theme for Season 1 of the anime Mobile Suit Gundam 00 and topped the Oricon Weekly Singles Chart.
It was also included on the album KISS, capturing the hearts of a wide audience from rock fans to anime enthusiasts.
For those who grew up loving anime and the Gundam series, it is surely a song that resonates even more deeply.
Re:memberFLOW

FLOW’s anime tie-up song themed around hope for the future and rebirth features striking, powerful guitar riffs and energetic twin vocals.
The lyrics, born from the band members’ experiences overcoming trials, carry a determination to move forward without forgetting the past and a message about the importance of walking together with your companions.
Released in May 2006 and used as the eighth opening theme for the TV anime Naruto, the song reached No.
12 on the Oricon charts and stayed on the charts for eight consecutive weeks.
It is also included on the album FLOW ANIME BEST Kiwami and remains a staple at their live shows.
It’s a recommended track for those who want to sing nostalgic anime songs or cherish memories with friends.
O2ORANGE RANGE

As the first opening theme for the anime Code Geass: Lelouch of the Rebellion R2, a powerful track was born that weaves mixture rock into a J-pop foundation.
Even among ORANGE RANGE’s works, YAMATO’s striking high-range vocals stand out, and the contrast with RYO’s low vocals gives the piece a sense of breaking new ground.
With a message layered over the chemical formula for oxygen and themes that synchronize with the protagonist’s rebellion and pursuit of freedom, the song reached No.
3 on the Oricon Weekly Chart after its release in May 2008.
It was included on the albums PANIC FANCY and ALL the SINGLES, and has continued to be loved through diverse arrangements, including covers in games such as THE iDOLM@STER and World Dai Star.
In karaoke, its energetic progression and memorable chorus make it a song that greatly lifts the singer’s spirits.
Ideaeufonius

‘Noein: To Your Other Self’ is a science fiction anime that aired from October 2005 to March 2006.
The opening theme is ‘Idea’ by eufonius, which ranked 94th on the Oricon charts.
whaleBuzy

This is a song released in 2004 by the dance and vocal group Buzy.
A version with different lyrics, titled “Venus Say,” was used as the opening theme for the anime Twin Spica.
The lyrics for both versions were written by Haruichi Shindō, the guitarist of Porno Graffitti.
Set to a stylish sound, the song portrays the inner conflict of changing from a child into an adult.
inner universeOriga

A track powerfully sung by Origa that evokes a near-futuristic sense of speed and a fragile, unsettled heart.
It was used as the opening theme for the anime Ghost in the Shell: Stand Alone Complex.
The composition is by Yoko Kanno.
As the same rhythm repeats, various accents are layered in, as if expressing inner unrest.
Another major feature is the lyrics, where English and Russian intersect; the progression of speaking about “imagination” and “self” in multiple languages strongly conveys the work’s atmosphere of the “unknown.”
In conclusion
For those who rushed home from school and glued themselves to the TV, and for those who stayed up late rubbing sleepy eyes to watch anime, I’m sure these picks felt nostalgic.
There are still many songs we haven’t introduced yet, and we’ll keep updating over time.
If you ever feel like hearing that song again, please drop by once more.
