wacci “I Became Someone Else’s Girlfriend” Music Video

Wacci, a rock band that made their major debut in 2012.

This song is powered by a single knockout phrase—the title itself, “I Became Someone Else’s Girlfriend”—a truly unbeatable line.

From there, it unfolds into a dramatically expanding rock ballad whose lyrics offer many moments you can genuinely relate to as you follow along.

And when the supremely emotional chorus hits, it’s a tearjerker.

It’s a slightly clingy yet empowering love song that makes you want to trace the feelings woven into it as you listen.

AI – Story

AI’s “Story” is filled with messages that resonate with the heart.

Released in May 2005, this song gently wraps listeners in warmth.

With powerful vocals and relatable lyrics, it has continued to stay close to many people’s hearts.

In 2014, it was chosen as the Japanese end theme for the film Big Hero 6, bringing it even more love from a wider audience.

Sing it at karaoke, and memories with friends or words of encouragement for yourself will surely come flooding back.

It may be hard to imitate AI’s vocals, but the power of this song will undoubtedly come through.

Gen Hoshino – Koi (Official Video)

It’s an irresistible song that captures the hearts of those in love.

It affirms diverse forms of love and carries a powerful message that you can choose your own path freely.

It drew attention as the theme song for the drama “We Married as a Job!” and was released in October 2016.

The “Koi Dance,” which became a social phenomenon, further boosted its popularity, making it one of Gen Hoshino’s signature songs.

It’s perfect for livening up a karaoke session or when you want to get into a romantic mood.

This track lets you fully enjoy its pop, upbeat rhythm and profound lyrics.

Masaki Suda 'Niji' (Rainbow)

Masaki Suda, who is not only an actor but also flourishing as an artist, is a highly popular singer-songwriter, especially among men in their 20s.

“Niji” is one of his works that I particularly recommend.

It’s an orthodox J-POP song, but you might feel it sits a bit on the higher side.

That’s because Suda’s natural vocal tone is high, not because the song’s range is especially wide.

Don’t worry about sticking to the original key—find a key that’s comfortable for you and give it a try.

FlowerORANGE RANGE40rank/position

Hana – ORANGE RANGE (Full)

ORANGE RANGE is a five-member rock band that captivates fans with songs that incorporate a wide range of musical styles and the impact of having three vocalists despite being a band.

Their 8th single “Hana,” used as the theme song for the film Be With You, is a lyrical number created under the catchphrase “the RANGE that makes you cry.” The contrast between the sentimental melody and the emotional rap is sure to stand out in karaoke as well.

However, since the original is performed by low-, mid-, and high-range vocalists, it spans a wide vocal range for a single singer.

If possible, we recommend singing it together with friends in different keys.

frecklesJUDY AND MARY41rank/position

Freckles – JUDY AND MARY (Full)

This song, which was the opening theme for the anime version of Rurouni Kenshin, is Sobakasu by JUDY AND MARY, the rock band led by YUKI.

When you think of Judy and Mary, this is the song that comes to mind! It’s a mischievous and cute rock tune.

The key is quite high, so it’s a perfect track for those who are good at hitting high notes!
