Crystal Kay Popular Song Ranking [2026] (21–30)

think of UCrystal Kay29rank/position

Crystal Kay’s “Think of U,” which was featured in a Docomo Kyushu commercial.

This track is an R&B number where her mellow vocals and harmonies blend beautifully.

The chorus has a particularly poppy melody, making it the highlight! Also, the song’s message—“I’m always thinking of you”—evokes the image of a child who has moved from their birthplace in Kyushu to the big city, keeping in touch with their parents by mobile phone, which fits the commercial’s theme perfectly.

So close like this…Crystal Kay30rank/position

The image of an independent woman in her thirties singing with a refreshing, empowering vibe fits perfectly.

It’s a song sung by a woman in unrequited love, thinking of the person she loves.

You can even imagine a forbidden love, like one between people of the same sex, where no matter how much she feels, it never gets through.

I can’t even count how many times this song has made my heart flutter.

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
