Songs with titles starting with 'O' [Great for karaoke and shiritori!]

Songs with titles starting with “O” often feature unique names—like those using characters meaning “dance” or “gold,” as well as Osaka-themed songs.

They also tend to be great for getting everyone fired up when singing! I can’t think of many off the top of my head, so I want to look some up…

This is a list that might come in handy at such times: songs with titles that start with “O.” Use it when you’re wondering, “What songs start with ‘O’?” and also as a prompt for shiritori or when choosing tracks at karaoke.

Cherry blossoms in full, resplendent bloomKEYTALK

This is a spring anthem that blends Japanese elegance with a sense of speed, evoking fluttering petals.

KEYTALK’s sound and twin vocals resonate pleasantly! The lyrics portray a faint love swaying through the turning seasons, making your heart skip a beat.

Its catchy melody perfectly captures the exhilaration of spring.

Serving as the opening theme for the TV anime “RIN-NE,” this single was released in April 2015.

It also made waves for bringing on NARASAKI as producer.

This powerful track, aligned with the anime’s worldview, garnered wide support, reaching No.

Isn’t it perfect for the season when hopes and anxieties about new beginnings mix together? Use it as background music for your commute or school run, and your step will feel lighter! It’s a classic tune for anyone who wants a positive boost in the cheerful weather.

Only One For MeONE N’ ONLY

The sound that makes you feel both the poignancy and warmth of twilight really sinks into the heart.

It’s a ballad by ONE N’ ONLY, included on their album ON’O released in April 2020.

Although they’re strongly associated with intense dance numbers, songs like this that let you really listen are truly wonderful, aren’t they? The lyrics of this track describe a resolve to keep walking forward with someone precious, even amid uncertainty, and that single-minded devotion is deeply moving.

The members have also shared a story about a live performance where it was supposed to begin in silence, but a voice asking for water for the mic accidentally got picked up.

I hope you’ll listen to this song when you’re feeling down or when you want to feel someone’s kindness.

You can even sense the delicate breath of the vocals, and it makes you feel like you can try your best again tomorrow.
