A night when I want to cryAYANE

Even when nothing seems to go smoothly, I want to stay true to myself instead of taking the easy, ordinary path! This is a song that encourages you with its positive portrayal of someone choosing to live in their own way, even as they struggle and suffer amid the rough waves of society.
When things aren’t going well, you might suddenly long for your family or find yourself reminiscing about a happy past romance.
But if you can think, “The pain I feel now is a trial for me—by overcoming it, I can become stronger!”, doesn’t it feel like you can keep going just a little longer?

It’s a striking song featuring realistic lyrics that vividly conjure the scene after a breakup, along with Yuuri’s emotionally charged vocals.
“Shutter” was originally a track Yuuri wrote for a project on his official YouTube channel, specifically for his friend, photographer JUN MIYASAKA.
Knowing it was created with a dear friend in mind—someone who had gone through a painful heartbreak—doesn’t it make you feel not only the sorrow of the breakup itself, but also the beautiful friendship in sharing that pain together?
somedaySaucy Dog

It’s a track from the album “Country Road” and one of Saucy Dog’s most popular songs, often cited as one of their signature works.
Saucy Dog has released many love songs, most of which are said to be based on lead vocalist Shinya Ishihara’s real experiences.
“Itsuka” is no exception—according to Ishihara himself, it was inspired by a woman he had confessed his feelings to five times since middle school.
You can really feel the raw emotion as he looks back sentimentally on the happy times spent with someone he admired.

A gemlike love song woven from evanescent yet beautiful poetic expressions and a crystal-clear singing voice.
While skillfully depicting scenes from nature, it delicately conveys the feelings of thinking about someone dear.
When Tota posted it on social media in June 2021, it quickly sparked a huge response.
In December 2022, it was selected as the tie-in song for a Pure Gummy web commercial, and the full version was released in February of the following year.
Recommended for those who want to face everyday reality while feeling the sorrow of losing someone precious and the strength to keep looking forward.
Song of the Eternal NightKami wa saikoro o furanai

A ballad included on the mini-album “A View on Lambda” by the four-piece rock band Kami wa Saikoro wo Furanai (God Does Not Roll Dice).
It’s a heartrending breakup song about longing for a girlfriend whose heart has drifted away.
Have you ever felt that the love you receive from someone is thinner than the feelings you have for them? Loving someone while sensing that difference in temperature can be pretty tough.
It’s only natural that you can’t forget the person you loved even after breaking up.
Rather than forcing yourself to forget, you might actually feel more refreshed if you let yourself sink fully into the sadness while listening to this song.
