SUMMER TIMENEWS
NEWS is an idol group that thrived in the 2000s.
Although the group saw many members leave, the classic songs they left behind are still loved by fans today.
Among their tracks, one I especially recommend is “SUMMER TIME.” It’s a bright song, but because each vocalist sings with a light touch, the whole piece comes together with a refreshing summer vibe.
It’s the perfect song to listen to while getting ready in the morning, don’t you think?
Pareo is emerald.SKE48
SKE48’s “Pareo wa Emerald” is a song charming for its summery freshness and cuteness.
Just listening to it makes you feel as if a pleasant summer breeze is drifting around you.
Released in 2011 as their sixth single, it features Jurina Matsui in the center position.
The lyrics tell a story of a girl who wears an emerald-colored pareo, blossoms beautifully, and a boy who falls in love with her—its poetic wording is another highlight.
With its simple, easy-to-remember melody, it’s also a great pick for karaoke when you want to enjoy a summery vibe.
