[For Women] Sing challenging songs at karaoke and steal the spotlight! (61–70)
Bluermilet

Singer-songwriter milet, known for her vocals inspired by Western music, has gained widespread popularity.
Among her many hit tunes, the one I especially recommend is “Bluer.” This track is one of her works with a particularly strong Western influence.
As a result, it features advanced vocal techniques—such as ad-libs and falls—that you don’t often hear in Japanese pop.
If you’re looking to level up your detailed techniques, definitely give it a try.
I am a cat’s eye.Shiina Ringo

This is Ringo Sheena’s 17th single, released in May 2023.
It was apparently produced as a commemorative work for the 25th anniversary of her debut.
Many of Sheena’s songs are known for their intriguingly complex melodic progressions and rhythmic phrasing, and this track is no exception—it’s filled with a highly distinctive and memorable melody.
Precisely because of that, if you can nail it at karaoke and reproduce it accurately, you’re sure to be the center of attention! Be sure to study the song and lyrics thoroughly before giving it a try.
If you sing with the sensation of placing your voice against your upper palate, you’ll likely achieve a vocal tone rich in higher overtones, similar to hers—definitely give that a try as well!
Pink BlueRyokushokushakai

This song is included on Ryokuoushoku Shakai’s fourth studio album, Pink Blue, which was released in May 2023.
The track we’re introducing here, Pink Blue, serves as the album’s title track, and its music video was released ahead of the album.
When singing this song at karaoke, the key points are not only how precisely you can trace the vocal melody, which moves intensely and intricately up and down, but also whether you can deliver with a powerful, resonant tone across both high and low ranges.
Combined with the slightly up-tempo feel, it’s quite a challenging song to sing; however, for those confident in their vocals, it’s one you should definitely try.
Efficiently converting breath into voice is crucial, so study that aspect as well—and be sure to practice carefully so you don’t strain your throat.
The Kouga Ninja ScrollsOnmyoza

This is Onmyo-za’s 10th single, released in April 2005.
It was used as the opening theme for the TV anime Basilisk: The Kouga Ninja Scrolls.
Set over an uptempo, hard-rock-style backing track, it’s a song that really lets vocalist Kuroneko’s high tones shine.
To sing this track convincingly, it’s important not only to deliver the high notes in your chest voice with openness and ease, but even more crucial is how smoothly you can transition between registers in the chorus sections that switch into falsetto.
Master those seamless register shifts, perform it brilliantly, and bask in the praise from everyone around you!
Crimson Lotus FlowerLiSA

It’s LiSA’s 15th single, released in July 2019.
It serves as the opening theme for the TV anime Demon Slayer: Kimetsu no Yaiba.
With its up-tempo, driving feel and a chorus built around high notes, it’s a song that, in a sense, clearly showcases the “difficulty of singing.” For that reason, it’s also one of the best choices if you want to draw attention at karaoke.
As you sing, be sure to pay close attention to shaping vocal dynamics throughout the song, using falsetto effectively, and switching smoothly between registers.
Six Trillion Years and an Overnight Storykemu

Released in December 2012, this is a classic, notoriously difficult Vocaloid song! It has a Japanese-style flavor; the intro is very relaxed, but the tempo suddenly speeds up and the lyrics are extremely dense.
You’ll need to be mindful of stamina, lung capacity, and explosiveness, but it’s highly recommended for those who love fast songs! The trick to singing the rapid-fire parts is not to try to articulate every single syllable; instead, clearly pronounce the vowel sounds that serve as accents.
Doing so helps you lock into the rhythm and sing more lightly.
With fast-tempo songs, you especially need to memorize the lyrics—otherwise in karaoke you’ll end up just chasing the words and sort of singing without intention.
I recommend first being able to hum the melody, then adding the lyrics afterward.
rock starAdo

Ado, who rose to prominence in her teens as a masked singer who never shows her bare face, has been taking the scene by storm with unstoppable momentum since her major-label debut in 2020.
Her unforgettable voice is supported by overwhelming power and a wide expressive range; both her forceful shouts and her falsetto carry a distinctive allure.
In April 2025, she released a track that clearly reflects the influence of Ringo Sheena, whom she has said she respects.
Featured on her first best-of album, “Ado no Best Album,” the song “Rockstar” fully showcases Ado’s aggressive side, built around a hard rock sound befitting its straightforward title.
While the song’s structure is relatively simple hard rock and the melody line isn’t overly complex, delivering it from Ado’s growling lows to her lustrous, powerful falsetto seems extremely challenging.
If you don’t keep your vocal folds firmly closed and master diaphragmatic breathing before attempting the shouts, you’ll quickly strain your throat—so be careful on that front.
