"1+1" is Sia’s sparkling invitation to turn simple math into pure magic. Pairing her Australian powerhouse vocals with French-Israeli singer Amir, the track blends English and French lyrics to show that when two people come together, the sum is far greater than its parts. Whether you picture a moonlit beach or a neon dance floor, Sia urges us to “give your all and give some more,” letting the beat dissolve every worry. One plus one becomes an anthem of unity, telling us that with music in our ears and someone by our side, every day can feel like a holiday.
From “sous le soleil quand il pleut” (under the sun when it’s raining) to “let the music free your soul,” the song paints a world where contrasts fade and colors mix. The bilingual chorus reminds us that love, rhythm and joy speak a universal language. So grab a partner, sway to the light and feel the energy multiply—because in Sia and Amir’s vibrant universe, two hearts always equal something beautifully bigger.
