A masterpiece sung by Kasane Teto. Recommended popular UTAU songs (1–10)
I'm a hopeless person!Lightly Salted Index
There are times when you just hate how hopeless you are, right? This song by Vocaloid producer Usushio Shisū was released in 2019.
As the title suggests, it’s a piece that sings and shouts about one’s own uselessness, with an upbeat band sound that really stands out.
The rolling, tinkling tone of the electric piano sticks in your ears, too.
It’s cute, and the down-to-earth lyrics are so relatable! Ruko Teto’s innocent voice fits perfectly.
By the time it’s over, it’s a rock tune that blows everything away! Highly recommended when you need a boost!
There was just a choice.Frokuro
I can only tip my hat to the sheer creativity and ingenuity.
This piece, released in 2021 by Frokuro, a Vocaloid producer known for experimental musicality, is one I’d love you to experience while watching the music video.
The track employs a clever mechanism: sixteen chords are prepared, each assigned a corresponding word; by rearranging their order and playing the chords, both the mood of the music and the lyrics shift.
The same sounds and words recur, yet it feels like it’s looping without actually looping… As you listen, a strange sensation is sure to swirl in your chest.
Life is short, fall in love, young maiden.Death Ohagi
The music production is by Desu Ohagi, and Teto’s vocal tuning is by Yurahonia-P.
It features an upbeat, catchy chorus.
It is included on Kasane Teto’s solo major-debut compilation album, “0401 – The Best Days of Kasane Teto.”
Girl who turns rightspring rain
The light guitar riff and poppy melody intertwine in such a satisfying way! This is a signature work by Vocaloid producer Harufuri, released in 2015.
The rhythmic band sound, which makes your heart feel buoyant, is striking.
It’s crafted so well that just following the flow of the sound is more than enough to enjoy it.
The lyrics convey an encouraging message of “Let’s move forward just as we wish,” making this a highly addictive Kasane Teto track! Be sure to listen at full volume!
I don't have a knack for living.Aotani
It’s a song that will especially resonate with middle and high school students! Created by Vocaloid producer Aotani and released in 2018.
Its relatable lyrics focus on the difficulties of living in modern society, which is a big part of its appeal—you can’t help but nod along and think, “I get it.” The fast-paced arrangement and catchy melody feel great to listen to, and your body starts to sway on its own.
Before you know it, you’ll feel like singing along! So it’s also highly recommended for karaoke.
Isn't it not okay!?NEW!solid beats
This is a Kasane Teto SV piece by Solidbeats released in October 2025.
It’s a song that gently reassures a heart shaken by anxiety and haste, saying “It’s going to be okay,” and its pop sound makes it uplifting.
A standout feature is a section that incorporates the motif of the nursery rhyme “Mary Had a Little Lamb.” The rhythmic track gives it an addictive quality that makes you want to move your body.
I think it’s perfect for anyone wondering, “Is it okay to stay as I am?” or as a song to send when you want to encourage a friend!
