The temperature rarely stops producers from putting out warm, summer-ready music, but now that the season actually reflects the sound, something like Tenma Tenma’s “Nettaiya” connects way more powerfully than if it was the end of February. The Osaka artist has put out some solid stuff before — see this winter’s Kitahama, though maybe that one would have connected more now — but “Nettaiya” swelters, a chirpy melody breezing over strums and a light beat, with the vocals adding a sweetness to the tropical-tinged number. Listen above.
