Delicious FridayCrystal Kay31rank/position

It also sounds like a cheer-up song for women who are swamped with deadlines and paperwork.
Because there’s a “delicious Friday,” you can start giving it your all again from Monday.
It’s an upbeat track that says, even though there’s a mountain of work piling up, just forget it all for now and have fun.

With lyrics that encourage you to be yourself and her powerful vocals, it’s a song that lifts your spirits.
MapleCrystal Kay34rank/position

This is the version sung by Crystal Kay, who has been active on the front lines since her debut at 13.
Featured at the very beginning of her first cover album, “I SING,” released in April 2021, this track offers a fresh, synth-driven electronic arrangement that contrasts with the original.
Arranged by Kazuhiko Maeda, the warm yet dance-influenced sound design brings out the charm of her voice.
Beneath the poignancy, a core strength quietly emerges, making it perfect for a night drive or moments of solitary reflection.
Savor a sophisticated, urban atmosphere that’s distinct from Spitz’s take.
Unrequited loveCrystal Kay35rank/position

It is also included on the 2004 selection album “CK5.” The song powerfully expresses the heartache of unrequited love.
girlfriendCrystal Kay & BoA36rank/position

Amazing, amazing! That’s the word.
I think both of them speak Japanese very well.
I can feel their desire to stay friends forever.
Hearing these two sing makes me feel that “true friendship that isn’t bound by trivial things” is the most wonderful thing of all.
We Who You Don’t Knowchay feat. Crystal Kay37rank/position

It was the theme song for the drama “Anata ni wa Watasanai,” starring Yoshino Kimura.
The song opens with a shocking phrase.
It leaves the impression that a serious woman can change this much when she falls in love.
Deep in a woman’s heart, there is a box that has never been touched before.
That box holds tremendous energy, turning a gentle woman into a passionate person.
unrequited loveCrystal Kay38rank/position

A bittersweet dance tune about a man she’s had a long-standing crush on who now seems to have a very close girl in his life.
All she can do is watch how perfect they look together, torn over whether she should give up.
The song conveys the anguish of not finding an answer.
