Like this all the way until morningKato Miria

Miliyah Kato’s classic “Konomama Zutto Asamade” (“All the Way Until Morning”).

As one of her early works, the song shows authentic R&B elements throughout.

You need a sense of groove to sing it, so rhythm is required, but the vocal line itself doesn’t have the kind of complexity typical of R&B.

In fact, because each phrase is short, it’s a song that doesn’t demand high-level foundational vocal technique.

If you’re not confident in your vocal power, consider adding this piece to your repertoire.

When Love Ends – Rin-ne (Official Music Video)
When love endsRin Oto

Born in 1999 and hailing from Fukuoka, Rin-ne is a rapper who’s gained popularity especially among younger listeners.

Rather than a hard-edged style, he’s known for a melodious approach that sits between mellow tracks, melody, and rap—earning support even from people who don’t usually listen to hip-hop.

“Koi ga Owareba,” a track from his third EP, “back alley,” released in December 2024, is quintessential Rin-ne: a standout song featuring a chill, lo-fi hip-hop-inspired track, melodious rap, and sharp, clever wordplay.

Overall, there are plenty of sections where the melody is sung, and if you learn the lyrics and the phrasing breaks, it’s approachable even for those who aren’t confident with rap—plus, it’ll sound cool at karaoke!
