Ken Hirai - Grotesque feat. Namie Amuro (MUSIC VIDEO YouTube ver.)

This is a collaborative song by Ken Hirai and Namie Amuro that sharply depicts the contradictions and conflicts lurking within the human psyche.

Released in April 2014 as their 36th single, it serves as a slightly twisted anthem for everyone wrestling with life.

The music video, themed around a courtroom, also drew attention, and the song reached No.

4 on the Oricon Weekly Singles Chart.

Offering a chance to confront one’s inner self, this track carries deep meaning for those of us living in the age of social media.

If you’re singing it at karaoke, it’s recommended for moments when you and your friends want to lay your true feelings on the table.

Sentimental / Ken Hirai (Cover)

A heartbreakingly sad breakup ballad that I highly recommend for this increasingly chilly season.

It’s a song by singer-songwriter Ken Hirai, included on his sixth album SENTIMENTALovers, released in 2004.

The tune and melody are gentle, and that very ease on the ears makes the lyrical message pierce the heart all the more.

You want them to feel the same way you do…

it makes your chest ache.

It’s a masterpiece best savored alone, giving it your full attention.

Ken Hirai 'I Fall in Love with You' MUSIC VIDEO

Boku wa Kimi ni Koi wo Suru is a straightforward, heartfelt song sung to a beloved person you’ll no longer be able to meet.

Released in 2009, it was used as the theme song for the film I Give My First Love to You.

Although the message is passionate, the melody is relaxed, making it easy to sing.

The chorus is a bit high in key while the other parts are relatively low, so be careful when setting the key.

That said, if you adjust the key properly, it’s a song that’s easy for anyone to try, regardless of gender.

Ken Hirai “Even If the Day Comes When We Part” MUSIC VIDEO

Precisely because we love, our hearts ache at the thought that a farewell will someday come.

Someday We’ll Have to Part, which captures that feeling, was released in 2008 and was chosen as the theme song for the film I Remember the Sky.

Its lyrics remind us that even happy days will one day end, which is why we should cherish the present and love the people we care about with all our hearts.

With its gentle melody and a range that isn’t too wide, it’s easy to sing.

Try singing it while thinking of someone precious to you.

Ken Hirai '1995' MUSIC VIDEO

A track from Ken Hirai’s first album in about five years, “Anataninaritakatta,” released on May 12, 2021.

Its music video was unveiled on May 5, ahead of the album release.

Not limited to this song, much of Ken Hirai’s music appears to be sung using mixed voice.

Speaking of mixed voice, it lies between falsetto and chest voice—a blend of the two—so in that sense, you could say this track is a treasure trove of diverse falsetto-like tones.

There are hardly any sections sung in what you’d call typical falsetto, but it’s a song you can enjoy as a showcase of varied vocal production.

If you’re confident in your falsetto, definitely try singing it at karaoke.

It’s also perfect as practice material!
