Ros's music featured three main types of music: Cuban music, Brazilian music and Caribbean calypsos. Of these genres, Cuban music was the most varied: it included the conga, the ballroom rumba, the mambo, and the cha-cha-cha. Ros introduced the Brazilian samba to England, and it became hugely popular. His "Wedding Samba" sold three millions copies in 78rpm, for example. He was very popular during the 1950s and 60's.
