J Balvin is already known for his work in the urban Spanish genre. Rosalía, a "newcomer", brings a quite surprising fresh take on urban music. With a background in Flamenco, Rosalía brings metaphorical lyrics, clever use of the Spanish language and... class, pun intended. ("Con Altura" traduces literally to "With High" but culturally means doing things with class, with quality and long lasting). Yet the biggest difference is that enters a urban genre recognized by its catchy tunes, over female sexualization and flat lyrics, to an interesting mental, visual and sound (minimalist and highly melodic) and makes it a one billion hit. Without a beach or a pool.
